My real work does not allow me to keep this FAQ up-to-the-minute. So I'm dumping new stuff into http://www-leland.stanford.edu/~llurch/win95netbugs/new.txt. Also see the list archive at gopher://quixote.stanford.edu/1m/win95netbugs. Stuff that I get while using trn or pine is saved to new.txt; stuff that I get while using NewsWatcher is saved to the gopher. Download these files to a UNIX system and point a mail reader at them, e.g. mail -f or pine -f new.txt. I believe Eudora will read the format too.

Content-Description: A.2. What's this about a Win95NetBugs email list?
Date: Sun, 24 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
win95netbugs@lists.stanford.edu is an unmoderated electronic mail discussion list for the purpose of sharing information and, hopefully, solutions to the networking bugs and "missing features" in Microsoft Windows 4.x.

It is intended as a relatively low-traffic list for network managers who know from whence they speak. I don't want any basic setup questions. We will cooperatively compile a FAQ file and Web page(s) for end users.

If you don't need any more mail littering your inbox, perhaps we could interest you in the archive of all messages posted to win95netbugs on gopher://quixote.stanford.edu. Currently the path is 1m/win95netbugs, but this is likely to change to separate directories for each month Real Soon Now.

The list is managed automatically by a majordomo list server. To subscribe to the list, send the command "subscribe win95netbugs" in the body of an electronic mail message to majordomo@lists.stanford.edu. Do not include your real name or email in the body of the message; it will be extracted from the From: header. This is important because if the From: header of subsequent messages don't match, they will be bounced to the list moderator.

For more information, email win95netbugs-request@lists.stanford.edu.

Please don't expose yourself to ridicule by posting administrative messages to the entire list!

Messages sent to the list by non-subscribers will be bounced to the moderator for review. Pertinent messages will usually be passed along with minimal delay. Spammers will be spanked.

All messages to the list are archived, redistributed on a gopher server, and physically become the property of Stanford University and other recipients, though you retain other rights associated with copyright.

Content-Description: A.3. What related resources are available?
Date: Sun, 24 Sep 95 18:09:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
There's far too many to list, but the quality is very uneven. Just see Yahoo's Win95 Page. Of special interest might be the official www.windows.microsoft.com and the unofficial www.windows95.com, which bills itself as "WINHQ." However, at this writing, all of the Win95 networking resources listed in Yahoo are SLIP/PPP guides written by nontechnical people. If you have a good guide, please list it in Yahoo and other directories.

For technical information on PC TCP/IP networking, see Bernard Aboba's excellent FAQ for the comp.protocols.tcp-ip newsgroup, which you can get from:

ftp://ftp.netcom.com/pub/ma/mailcom/IBMTCP/ibmtcp.zip
http://www.zilker.net/users/internaut/update.html
Another useful page from the loyal opposition (David really likes Win95), is Windows95 Annoyances, http://www.ocf.berkeley.edu/~daaron/win95ann.html.

Microsoft publishes selected known problems and workarounds in the Windows Knowledge Base, http://www.microsoft.com/kb/indexes/windows.htm. The keywords "kbnetwork," "3rdPartyNet," and "win95" are useful to know.

Content-Description: B.1. SAP advertisement kills IPX routing, poses security problems
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
Win95 can be configured to masquerade as a NetWare server/router. This will cause rather severe problems in many situations. See CSUN's brief description of the problem at http://rcr.csun.edu/ntg/win95.html#novell. The CSUN page does not detail the steps to steal NetWare passwords with Win95, but it's not hard to imagine. I believe InfoWorld, Communications Week, PC Week, and most other trade publications covered the issue as long as nine months ago, but Microsoft has not fixed the problem.

Another good explanation of the problem is at http://www-leland.stanford.edu/~llurch/win95netbugs/IPX-SAP-Bug.txt.

One of Microsoft's developers wrote a rather lengthy response to this issue. It is saved at http://www-leland.stanford.edu/~llurch/win95netbugs/MS-SAP-Response.txt.

Microsoft acknowledges that the frame type used for IPX/SPX packets must be set manually because the default "Automatic" frame type detection does not work. You need to open IPX/SPX Compatible Protocol/Properties/Advanced and select it manually. There is a picture at http://www-dccs.stanford.edu/NetConsult/Win95Net/ipxprops.GIF.

Content-Description: B.3. What does Novell recommend regarding Win95 and NetWare?
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
Novell recommens that you use the existing NetWare Client version 1.2, which works just fine under Win95 and provides access to all services. Win95's Network Control Panel even has an install script for it. Microsoft will also tell you to use Novell's drivers if you have any trouble. For more information from Novell, see http://netwire.novell.com/servsup/win95/win95.htm. The public release of a Novell 32-bit client is coming soon. An alpha version was inadvertently (?) put in a public download area last month, and looked promising.

Content-Description: B.4. Win95 Crashes NetWare 3.12 server.
Date: Wed, 13 Sep 1995 03:07:25 GMT
From: zim@grayfox.svs.com (Jason Zimberoff)
Update: Fri, 10 Oct 1995 00:00:00 GMT
There have been many reports of Win95 clients causing NetWare servers to crash. In all cases that we know of, the problem wasn't Win95, per se, but the packet burst mode that it supports by default. Older servers can't handle packet bursts, a late 3.12/4.0 performance enhancement.

There are two ways to resolve the problem of packet bursts:

  1. Get the file pburst.exe from Novell's BBS or Internet servers and install the patch on your server.
  2. Disable packet burst on the Win95 clients by adding the following to system.ini:
     [nwredir]
     supportburst=0

Content-Description: B.5. How do I enable Long File Name support on a NetWare server?
Date: Tue, 10 Oct 1995 20:00:00 GMT
From: Rich Graves <llurch@networking.stanford.edu>
Just install the OS/2 namespace. This requires NetWare 3.12 or a patched 3.11. Most of the time, it seems to work. If Win95 clients crash your server or something, remove the OS/2 namespace and see the next question. I am not a CNE! Don't ask me!.

Because of a little bug, Win95 will not use long file names on 3.11 servers when you use Policy Editor to tell it to do so. The easier workaround is to add the following to system.ini:

     [nwredir]
     SupportLFN=2
For more information on this problem, see article Q137275 in the Microsoft Knowledge Base.

Content-Description: B.6. How do I disable Long File Names on a Win95 client so I can use a server without LFN support?
Date: Tue, 10 Oct 1995 20:00:00 GMT
From: Rich Graves <llurch@networking.stanford.edu>
Contributions by ramesh@scr.siemens.com (Ramesh Viswanathan) and edwardd@finance.ci.seattle.wa.us.

What I was referring to here was some setup which is allegedly necessary to make Win95 actually *work* with the OS/2 namespace.

However, if you run POLEDIT (it's on the CD in admin\apptools\poledit) and open the registry, you can then go to Local Computer, Network, Microsoft Client for Netware Networks, and turn off use of long names on the server.

Alternatively, add the following to system.ini:

     [nwredir]
     SupportLFN=0

Content-Description: B.7. Can I get NetWare broadcast messages (like "low on disk space") on Win95?
Date: Sun, 24 Sep 1995 20:00:00 GMT
From: Rich Graves <llurch@networking.stanford.edu>
Contributions by Don Zimmer (drzimmer@ionet.net) and "ClubWin" member ramesh@scr.siemens.com (Ramesh Viswanathan)

By default, Win95 machines using Microsoft's 32-bit NetWare client do not receive NetWare broadcast messages. Novell recommends using their existing version 1.2 real-mode drivers and NWPOPUP instead.

You could also put WINPOPUP.EXE in AUTOEXEC.BAT or your Startup folder. However, there's apparently no way to remove WINPOPUP from the task list or to stop users from quitting it.

Yes, you can, with WinPopup, provided that IPX/SPX is your default protocol. However, messages are limited to 38 characters, and there are other limits. See article Q120223 in the Microsoft Knowledge Base.

Bizarre. When you try to mount a server with \\ or net use, does anything
happen? Attach an external transceiver with idiot lights and watch the
transmit/receive activity.

You could look in C:\BOOTLOG.TXT for a record of what happens at startup.
Not that you'll be able to understand it...

From: Rich Graves <llurch@networking.stanford.edu>
Win95's built-in peer-to-peer sharing capabilities don't work over the built-in IPX/SPX="compatible" protocol with share-level access control. You need to enable user-level access control with an NT or NetWare server for authentication. See article Q131354 in the Microsoft Knowledge Base.

If your Novell NetWare login script contains a DISPLAY command with a very long path, or uses an environment variable containing a very long path, some information may not be displayed correctly. An internal buffer is too small. Use a shorter path or environment variable. See article Q132763 in the Microsoft Knowledge Base.

Well I solved my own problem and here's the answer for anyone else
that experiences similar things.

My computer name in Control Panel | Network | Identification was the
same as my Netware logon name.  Once I changed this it processes the
login script and maps all the drives just fine.  I guess there's some
kind of conflict when the name of the machine and the logon id are the
same.

Content-Description: C.1. No interface for changing MTU or RWIN settings.
Date: Sun, 24 Sep 95 21:15:21 -0800
From: Rich Graves <llurch@networking.stanford.edu>
By default, Win95 uses the largest value of MTU possible for the chosen media type. Most people who used the excellent 16-bit Trumpet Winsock, whose FAQ is at http://www.trumpet.com.au/wsk/faq/wskfaq.htm, configured these parameters for optimum efficiency and response, and really miss Trumpet's interface for setting them. This excerpt from the Resource Kit, © 1995 Microsoft Corporation, tells how to add an MTU setting with REGEDIT.EXE:

The entries in this section must be added to the following Registry key, where n represents the particular TCP/IP-to-network adapter binding.

Hkey_Local_Machine\System\CurrentControlSet\Services\Class\netTrans\000n

MaxMTU = 16-bit integer

Specifies the maximum size datagram IP that can pass to a media driver. SNAP and source routing headers (if used on the media) are not included in this value. For example, on an ethernet network, MaxMTU will default to 1500. The actual value used will be the minimum of the value specified with this parameter and the size reported by the media driver. The default is the size reported by the media driver.

RWIN is a TCP-specific thing, but maybe this question should be moved to the General/Dialin section anyway?

Content-Description: C.2. Netscape Packet Storm Bugs.
Date: Sun, 01 Oct 95 21:31:42 -0800
From: Rich Graves <llurch@networking.stanford.edu>
This appears to be a bug specific to Netscape, but it's worth mentioning here because so many people use it. Netscape 1.2N, 32-bit version, does not back off from TCP RESETs and ICMP unreachable messages; instead, it retransmits forever, with no timeout. On a dialup connection this will only cause some annoying "hangs," inducing the user to hit the "Stop" and "Reload" buttons a lot, but it can cause destructive packet storms on Ethernet and other high-bandwidth links.

Please see the initial post about this set of bugs at http://www-leland.stanford.edu/~llurch/win95netbugs/Readme-Netscape_Net_Bug.txt. That tells where to get relevant packet traces.

Two URLs you can try to check for these bugs are http://ftp.netscape.com (responds with a TCP RESET) and http://36.36.0.10 (nonexistent network, responds with an ICMP unreachable).

The Netscape product manager posted a message claiming the problem was irreproducible, to which I posted a response. Anyway, you can probably reproduce the problem yourself with the URLs above. You need some technical knowledge of the Internet Protocols TCP to understand the problem.

Content-Description: C.3. Web browser/TCP connection "hanging" bug.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
I suspect that this is a separate bug from the Netscape bug above. Netscape, the Microsoft Internet Explorer, and other multithreaded Internet apps seem to lose track of multiple TCP connections. The usual symptom is a page that stops loading halfway, but works fine if you hit Stop or Reload. Setting MaxConnections=1 will usually fix this problem.

Three people have reported this on different machines. It seems to happen fairly rarely. Basically it seems the NetBIOS name widget gives the TCP/IP encapsulation widget bad information sometimes. For a week this was 100% reproducible on my machine, through an OS reinstallation and several Safe Mode reboots. I wrote a post saved at http://www-leland.stanford.edu/~llurch/win95netbugs/Readme-MSClientDNSBug.txt.

Content-Description: C.5. Interoperability with BootP servers.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
Microsoft's chose to implement DHCP in a way that is not interoperable with BootP. One surmises they wanted to sell more NT DHCP servers.

John Wobus's DHCP FAQ, at http://web.syr.edu/~jmwobus/comfaqs/dhcp.faq.html, might be of interest. There are some hybrid BootP/DHCP servers out there, but they don't all interoperate, and your routers might need to be upgraded to handle the kind of DHCP replies Microsoft likes. Anyway, read John's FAQ. If you absolutely can't get it from the Web, you can ping him at jmwobus@syr.edu.

Two Guys and a Vax (www.tgv.com, sales@tgv.com) have announced a replacement TCP/IP stack for Windows 95 that handles BootP properly, and some other highly desirable features. They also make some rather nice applications. Demos are available. Of course they want real money for this stuff.

Content-Description: C.8. Default hostname resolution order (broadcast-WINS-DNS-LMHOSTS) is non-ideal for my site; how can I change it?
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
I would think that the name resolution should work in precisely the opposite direction. Check the local LMHOSTS mappings first, then DNS, then WINS, and only as a last resort broadcast on the local subnet. Oh well.

This extract from the Resource Kit comes from Daniel M <puppet@mail.dynamsol.com. This does not seem to apply to the 32-bit WinSock; could anybody tell me about that?

Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP\ServiceProvider

The following keys describe the order used to resolve host names. A lower number
sets a higher priority for name resolution. These settings are used for 16-bit
Windows Sockets, which need to rely on the resolvers that are expected to take
the least time.
 
The numbers indicate the default values specified in Windows 95.

LocalPriority = 499
HostsPriority = 500
DNSPriority = 2000
NetbtPriority = 2001

Content-Description: C.9. DNS lookup timeout is ridiculously long.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
Most apps will freeze the machine while doing a DNS lookup, which is really annoying, especially since the timeout for DNS lookups is so long, especially in those weird places like Cornell and Clemson where Win95 doesn't seem to like the local DNS server. The "NameSrvQueryTimeout" in the Registry, which some people have pointed out, seems only to apply to Microsoft's proprietary WINS service, not Internet standard DNS.

There's gotta be a way to set this; anybody?

Yes, you have accurately diagnosed the problem win Win95 uploads, commonly
seen in mail and news programs.

To fix this, open the Registry and set one or both of these:

 Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP

 PMTUBlackHoleDetect = 0 or 1

 Specifies whether the stack will attempt to detect Maximum Transmission
 Unit (MTU) routers that do not send back ICMP fragmentation-needed
 messages. Setting this parameter when it is not needed can cause
 performance degradation. The default is 0.

 PMTUDiscovery = 0 or 1

 Specifies whether Microsoft TCP/IP will attempt to do path MTU discovery
 as specified in RFC 1191. The default is 1.

It would be *nice* if there were a Knowledge Base article on this, or if
the people answering the $1.95 per minute network support lines had *just
one* clue.

Setting MTU to some ridiculously low value will also work, but
it hurts
performance.

The TGV and what's-his-name replacement TCP/IP stacks for Win95 will
fragment properly according to existing Internet standards.

Content-Description: C.11. What commercial-quality TCP/IP stacks are available to replace the stack that Microsoft supplies?
Date: Sun, 24 Sep 1995 20:00:00 GMT
From: Rich Graves <llurch@networking.stanford.edu>
TGV (www.tgv.com), email sales@tgv.com (TGV stood for Two Guys and a Vax many years ago before they got successful and went legit), has announced MultiConnect 1.2 for Win95 and WinNT. It will ship in early October. It supports NetBIOS over TCP/IP. Nice clients for Telnet, FTP, News, and WWW, plus an NFS client and server, are included if you need them, or you can get a single copy of the stack only for just $100 (volume discounts and site licenses available).

Core Systems, http://www.win.net/~core/, email lvuong@cores.com, has announced and is now shipping INTERNET-CONNECT for Windows 95. In addition to the features of Win95's stack, it supports BootP and includes better telnet and FTP clients. It does not support NetBIOS over TCP/IP, so you can't use Windows file/print sharing over this protocol. Demos are available.

Join the crowd (though some people say it works for them). It's not clear why Microsoft included a script to install PC/NFS in the Network Control Panel. I guess they wanted it to look like NFS was available for Win95. Sun now has a patch available.

Betas and first releases of NFS for Win95 are available from Beame & Whiteside and others, but that's beyond the scope of this FAQ. You could also make your UNIX machines speak Microsoft's proprietary SMB protocol by installing SAMBA (reference?).

"Usually." Trumpet will, and it's significantly faster than Win95's SLIP/PPP support. On the downside, TCP/IP stacks designed for Windows 3.x, even those based on 32-bit VxDs, will only support 16-bit TCP/IP clients. So you can't run 32-bit Netscape or Microsoft Exchange. For Win95 instructions and the latest information on the work on a 32-bit Trumpet, see the Trumpet FAQ, http://www.trumpet.com.au/wsk/faq/wskfaq.htm.

That's right, they don't. You need to "upgrade" to Windows 95's included 32-bit TCP/IP, or one of the competitive commercial stacks, section C.11. For instructions, see A.3., related resources. If you use a modem, the Microsoft/Shiva package will be slower. Over Ethernet, on the other hand, Microsoft's stack is significantly faster than any 16-bit stack.

Open the Registry to:

Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP

BroadcastAddress = broadcast address in hexadecimal

Specifies the address to use for NetBIOS name query broadcasts. The default
is based on the IP address and the subnet mask.

BcastNameQueryCount = integer

Specifies the number of times the system will retry NetBIOS name query
broadcasts. The default is 3.

BcastQueryTimeout = milliseconds

Specifies the period of time the system will wait before timing out
broadcast name queries. The minimum value is 100. The default is 750.

BSDUrgent = 0 or 1

If this value is 1, specifies that Microsoft TCP/IP is to treat urgent data
the way some UNIX systems do (with a maximum of 1 byte of urgent data, for
example). If this value is 0, it specifies that the stack is to handle
urgent data as specified by RFC 1122. The
default is 1.

CacheTimeout = milliseconds

Specifies how long NetBIOS names are cached. The minimum is 60000
milliseconds (1 minute). The default is 360000 milliseconds (6 minutes).

DeadGWDetect = 0 or 1

Specifies whether Microsoft TCP/IP will use another gateway if the current
default gateway seems to be down. The default is 1.

DefaultRcvWindow = 16-bit number

Specifies the default receive window advertised by TCP. The default is
8192.

DefaultTOS = 8-bit number

Specifies the default type of service (TOS) for IP packets initiated by
Microsoft TCP/IP. The default is 0.

DefaultTTL = 8-bit number

Specifies the default time to live (TTL) for IP packets from Microsoft
TCP/IP. The default is 32.

DnsServerPort = port

EnableProxy = 0 or 1

If this value is 1, specifies that this computer is a WINS proxy agent. The
default is 0.

EnableRouting = 0 or 1

Specifies whether to enable static routing. Microsoft TCP/IP does not
supply a routing protocol, so all route table entries must be entered using
the route command. The default is 0.

IGMPLevel = 0, 1, or 2

Specifies the level of support allowed for IP multicast, corresponding to
the levels in RFC 1112. The default is 2.

InitialRefreshT.O. = milliseconds

Specifies the interval over which to contact WINS to refresh the name. The
minimum is 16 minutes, and the maximum is approximately 50 days
(0xFFFFFFFF). The default is 960000 milliseconds (16 minutes).

KeepAliveTime = 32-bit number

Specifies the connection idle time in milliseconds before TCP will begin
sending keepalives, if keepalives are enabled on a connection. The default
is 2 hours (7200000).

KeepAliveInterval = 32-bit number

Specifies the time in milliseconds between retransmissions of keepalives,
once the KeepAliveTime has expired. Once KeepAliveTime has expired,
keepalives are sent every KeepAliveInterval milliseconds until a response
is received, up to a maximum of MaxDat a Retries before the connection is
aborted. The default is 1 second (1000).

LmhostsTimeout = milliseconds

Specifies the period of time the system will wait before timing out when
seeking LMHOSTS for name resolution. The minimum value is 1000 (1 second).
The default is 10000 (10 seconds).

MaxConnections = 32-bit number

Specifies the maximum number of concurrent connections. The default is 100.

MaxConnectRetries = 32-bit number

Specifies the number of times a connection attempt (SYN) will be
retransmitted before giving up. The initial retransmission timeout is 3
seconds, and it is doubled each time up to a maximum of 2 minutes. The
default is 3.

MaxDataRetries = 32-bit number

Specifies the maximum number of times a segment carrying data or an FIN
will be retransmitted before the connection is aborted. The retransmission
timeout itself is adaptive and will vary according to link conditions. The
default is 5.

NameServerPort = port

Specifies the UDP port on the name server to which to send name queries or
registrations. The default is 137.

NameSrvQueryCount = integer

Specifies the number of times the system will try to contact the WINS
server for NetBIOS name resolution. The default is 3.

NameSrvQueryTimeout = milliseconds

Specifies how long the system waits before timing out a name server query.
The minimum is 100. The default is 750.

NameTableSize = integer

Specifies the maximum number of names in the NetBIOS name table. The
minimum allowable value is 1 and the maximum is 255. The default is 17.

Specifies the mode of NetBIOS name resolution used by NetBIOS over TCP/IP,
where 1 = b-node, 2 = p-node, 4 = m-node, and 8 = h-node. This value can be
configured using DHCP. The default is 1 (b-node), if no value is specified;
if WINS servers are specifi e d and NodeType is not, then the default is 8
(h-node).

PMTUBlackHoleDetect = 0 or 1

Specifies whether the stack will attempt to detect Maximum Transmission
Unit (MTU) routers that do not send back ICMP fragmentation-needed
messages. Setting this parameter when it is not needed can cause
performance degradation. The default is 0.

PMTUDiscovery = 0 or 1

Specifies whether Microsoft TCP/IP will attempt to do path MTU discovery as
specified in RFC 1191. The default is 1.

RandomAdapter = 0 or 1

For a computer with multiple network adapters, specifies whether to respond
with an IP address selected randomly from the set of addresses on the
computer or whether to return the IP address of the adapter that the
request came in upon. The default is 0 ( not random; that is, return the
address of the adapter that the request came in on).

RoutingBufSize = 32-bit number

Specifies the total amount of buffer space to allocate for routing packets.
This parameter is ignored if EnableRouting=0. The default is 73216.

RoutingPackets = 32-bit number

Specifies the maximum number of packets that can be routed simultaneously.
This parameter is ignored if EnableRouting=0. The default is 50.

SessionKeepAlive = milliseconds

Specifies how often to send session keepalive packets on active sessions.
The minimum is 60 seconds. The default is 3600 seconds (1 hour).

SessionTableSize = integer

Specifies the maximum number of sessions in the NetBIOS session table. The
minimum allowable value is 1 and the maximum is 255. The default is 255.

SingleResponse = 0 or 1

For a computer with multiple network adapters, specifies whether to send
all IP addresses on a name query request from WINS. If this value is 1, the
system will send one address in a name query response; if 0, it will return
all the addresses of its adap t ers. The default is 0.

Size/Small/Medium/Large = 1, 2, or 3

Specifies how many buffers of various types to preallocate and the maximum
that can be allocated, where 1 = small, 2 = medium, and 3 = large. The
default is 1; the default is 3 if the WINS proxy is enabled.

It's a common belief that windows 95 can't do IP forwarding (There were
several postings about it in comp.os.ms-windows.win95) and you have to use
NT to do it.

Win95 resource kit help file contains the following information:
[----]
Hkey_Local_Machine\System\CurrentControlSet\Services\VxD\MSTCP\EnableRouting = 0
or 1 
Specifies whether to enable static routing. Microsoft TCP/IP does not supply
a routing protocol, so all route table entries must be entered using the
route command. The default is 0.
[----]
I tried that on two machines (486DX2 and PENTIUM-75, both with ethernet card
and a RAS driver installed) and on both got a total system crash on boot (I
guess when loading vip.386).

Interesting enough, this whole routing issue has never been documented by
microsoft.

So, anybody "been there, done that" ?
Is it a bug, half-imlemented feature or just wrong configuration ?

Date: Tue, 10 Oct 95 23:30:00 -0800
From: Rich Graves <llurch@networking.stanford.edu>
WFW and NT have an "enable DNS for WINS resolution" checkbox that is turned off by default. In Win95 this feature is on by default, and there is no check box to turn it off. It turns out that this is what the "EnableDNS" switch in the Registry is for. If you turn it off, DNS is still enabled; it just isn't used for WINS resolution. This is part of Win95's redefinition of "intuitive." From article Q137368 in the Microsoft Knowledge Base:

How to disable NetBIOS name resolution on a domain-name system (DNS) while retaining other DNS functionality.

To disable NetBIOS name resolution on a DNS server, change the string value

Microsoft proposed some extensions to IPCP to negotiate the DNS server
and the NetBUI server.  The IETF rejected them as this was the wrong
level to do this.  Microsoft decided to ignore the IETF and implement
them anyhow.  Microsoft should provide a way to not use them (since
they are totally non-standard and are only supported by Microsoft
clients).  Users of Microsoft networking products would need to
contact Microsoft to determine how to do this.

This note is meant to be an explanation of what is happening and should
not be interpreted in any way as an offical statement by BSDI on The
Microsoft IPCP Options.

Content-Description: D.2. Degraded SLIP/PPP performance versus Trumpet.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
There have been a heck of a lot of posts in comp.os.ms-windows.win95.setup complaining that file transfers using Win95's native SLIP/PPP are slower than they were using Trumpet WinSock. There have been lots of posts that say performance is OK, but I don't recall any claiming that performance has improved.

The problem is probably rooted in the fact that when you use Win95's built-in SLIP/PPP, you're really using two protocol stacks, a TCP/IP stack built by Microsoft, and a remote access stack developed by Shiva Corporation, so you've got extra overhead to deal with.

Here are some general tips applicable to any dialin protocol:

Some of us in a local news group have discovered a nasty problem that
causes Win95 to lock up solid. Does anyone have a fix for this or can
anyone at least let MS know about it? The tech support lines are very
useless right now. An excerpt from the conversation follows. Thanks!

Content-Description: D.4. Minor changes to TCP/IP or modem parameters cause dialup properties to reset to defaults without warning.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Neil Moodie <nmoodie@c031.aone.net.au>
When making network config changes (often small, unimportant, insignificant etc changes), the properties of the dial-up connection are reset back to defaults. These defaults include PPP transport, with "server assigned" IP address and "server assigned" name server address.

This caught me out a few times, as I have a locally assigned name server address and have had to re-enter this information into the dial-up connection properties TCP/IP Settings after making minor changes to the dial-up config. Even configuring a new modem can reset these settings.

Content-Description: D.5. Win95 creates fictional COM ports on some plug-and-pray machines.
Date: 23 Sep 1995 03:28:47 GMT
From: oturn@gulf.net (Oran Turner)
The "phantom" com port seems to be a common problem with PNP motherboards and internal modems. I have a mouse on COM1 and an internal modem on COM2, with my physical COM2 turned off in BIOS. This is the problem...in the "Device Manager" in Windows 95, under "Ports (COM & LPT)", not only are my standard COM1, COM2 & LPT1 ports listed, but also listed is another entry labeled only "Communications Port." The settings for this extra entry correspond to the settings for COM1 (IRQ 4, I/O 03F8-03FF). I simply disable this extra entry to avoid the conflict the system detects, and everything seems to work fine.

Probably 90% of the phantom port problems are related to the interaction between an internal modem, a physical COM port, a PNP system and Windows 95. I've brought the problem to the attention of my motherboard manufacturer, but they pretty much blew me off. (I've got an Asus P55TP4XE.)

(Much Deleted) I had the same problem and was able to resolve it by putting a delay statement immediately before the "endproc" line. It appeared that the script routine was closing off before the server parsed back the Dynamic Address. I found a delay of anywhere between 2 and 5 seconds was sufficient.

Content-Description: D.7. Modem on COM4 incompatible with S3 video cards.
Date: 6 Oct 1995 07:43:12 GMT
From: tatosian@plough.enet.dec.com (Dave Tatosian)
If you have an S3-based video card (most 64-bit cards including #9 and Diamond), you cannot use COM4 because of a memory base address conflict.

These cards use port addresses (46E8h, in the case of S3) for 8514/XGA support, which will be *aliased* to address 2E8h by most COM port address decoders - which tend to only decode the low order 10 bits of the address field. Putting a modem on COM4 therefore ends up in conflict with the graphics card - but it's usually only apparent when the graphics card is running in a mode other than straight VGA (ie: in DOS, you won't see a problem, but running in Windows/Win95 in say 800x600, you will).

The solution is to move the modem to some other port address, but of course you have to avoid conflicts with your other COM ports. If your mouse is on COM1, and COM2 is free, you should use COM2. But if you want to keep your COM2 available for a serial port, you can't use the "standard" COM3 setup for the modem, because COM3 normally uses IRQ4 (which will conflict with COM1).

But you *can* set the modem up to use COM3 with *IRQ5* (most modems will support this configuration). That way, you won't conflict with COM1's use of IRQ4. If IRQ5 is already being used by a sound card, switch the sound card to use IRQ7 instead.

After making the required changes to the modem (and sound card if required) you'll have to make sure that Win95 does the right thing on startup. It should detect the new configuration and make the appropriate changes to the properties and resource allocations, but you should check under Control Panel-System-Device Manager to be sure. If needed you might have to set some of the resources manually. Back to index

waung@mprgate.mpr.ca (William Waung) reports that he could not establish a PPP connection to his Xyplex terminal server unless he disabled IP compression. More investigation is needed. You can see his message and followups on the win95netbugs list archive, gopher://quixote.stanford.edu/1m/win95netbugs, under the subject "Internet connection failure: no network protocol compatibility." Or look for his original newsgroup post to comp.os.ms-windows.win95.* on the www.dejanews.com searchable USENET archive. To help you recognize the symptoms, the error entries in his PPP log referred to problems with CCP (protocol 80fd). If you also run into problems with PPP-level compression (not modem-level compression), please mail win95netbugs-owner@lists.stanford.edu.

Newsgroups: comp.os.ms-windows.win95.misc

Here is some information that may help someone experiencing slower
than expected downloads.    For the good of the order:

Start by ensuring that your machine is not doing extra work by
compressing data unnecessarily.

Double click on My Computer / Dial Up Networking
Right Click on Prolog Icon (or what ever you called it on your
machine)
Click on Properties / Server Type
Remove all checks from boxes except for the TCP/IP box.

Next, let's be sure that your modem is answering your computer
correctly:

Click Start / Settings / Control Panel
Double click on Modem 
Click on Diagnostics
Click Com2 (or what ever port your modem is assigned)
Click More Info
Mine says:
Port COM2   
Int 3
Addr  2F8  
UART NS 16550AN
Highest Speed 115K Baud

Another trick you might try is to change your modem driver to the
Supra 288i.  See if that makes any difference compared to the Hayes
288 settings.  Don't know how you feel about those "standard"
selections, but I am not a fan of default settings.

Content-Description: E.1. No way to specify protocol to use for a specific service.
Date: Sun, 17 Sep 95 22:30:47 -0800
From: Rich Graves <llurch@networking.stanford.edu>
Say I want to connect to UTAH, my local NetWare server, but my default protocol is NetBIOS and I also have TCP/IP enabled. Maybe I have NetBIOS-over-IPX turned on, too.

As far as I can tell, I have to browse for \\UTAH on all protocols in series. Broadcast over NetBIOS, maybe go to a Browse Master, and wait for a timeout; Broadcast over TCP/IP, check the WINS server, check the DNS server, check LMHOSTS, perhaps :including a file cross-mounted from another server, and wait for a bunch of timeouts; and only then will my machine deign to look for UTAH over IPX/SPX.

This is inefficient, wastes time, and wastes bandwidth on slow links.

It's fun ------ I'll agree with you on that one. I battled with this
for about 4-5 months until I discovered an obscure little paragraph on
Microsoft Technet describing how to do it. Two solutions:
First
If you are loading stuff real mode you can use NETBIOS.EXE real mode
and it will work.
Second
But then again what's the advantage of '95 without 32 bit drivers.
Here's the trick. 
Go to the Network Control Panel
Select IPX/SPX Compatible Protocol
Select the Advanced Tab
At the bottom of the window you will see a check box saying "Set this
protocol to be the default protocol"
Once you've done that it should work. I've found performance to be
significantly better as well.

Yes, I had encountered this problem very early in the Beta, and microsoft is
aware of this problem.  I have been able to reset it using the registry as
follows:

1. Start Regedit and search for the Key word Telnet
2. Stop when you find the key: \HKEY_CURRENT_USER\Software\Microsoft\Telnet
3. On the Right hand Window Pane, double click on the Item that says Rows

From article Q135279 in the Microsoft Knowledge Base:

When you are browsing the network, Windows 95 stores the domain names in a table that is limited to 64K in size. When this table is full, no more domains are displayed.

In addition, many WINS servers have a known problem that causes them to report that domains exist, even after these domains have been removed from the network. On large networks, or on networks where domains are frequently removed shortly after they are created, this problem may prevent domains that currently exist on the network from being displayed in Network Neighborhood.

Microsoft has confirmed this to be a problem in Microsoft Windows 95. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

I am using %username% but it took a lot of digging. You need two
programs-PUTINENV and WINSET (on the win95 CD). I am using NT server
with a logon script. The game is to get the environment variables of
the user who just logged on using PUTINENV L and then to put this
info into the Win95 master environment with WINSET. You then can map
a drive to the user's home directory and have all the benefits of
the %username% variable. Below is my login script -- hope this helps.

if %os%==Windows_NT goto END 

\\server\netlogon\putinenv L
 
\\server\netlogon\winset username=%username%

net use f: /home

Content-Description: G.1. NE4100 Incompatibility.
Date: Sun, 17 Sep 1995 16:49:46 -0700
From: Nick Sayer <nsayer@quack.kfu.com>
The NE4100 PCMCIA card is not compatable with win95, despite being on the HCL. Here's the story:

What I believe is happening is that the NE4100 "support" simply is to just run with an NE2000 driver when you see an NE4100. This is not quite the correct thing to do.

Real NE2000 cards have a small ROM in their I/O space that contains the Ethernet address. A PCMCIA card has to have about a K of attribute ROM located elsewhere anyway in order to describe the card to the card-n-socket services. The folks who make PCMCIA NE2000 cards didn't bother to put the extra Ethernet address ROM in the I/O space as well, they simply placed the Ethernet address in the attribute ROM (usually at 0xff0) and left it up to the enabler or driver to do the right thing.

win95 does not do the right thing. It will use ff:ff:ff:ff:ff:ff as the Ethernet address for an NE4100. I reported this to the $35 tech support line and even more detail than the above paragraph. I told them exactly how a PCMCIA NE2000 differs from a real one. I even gave them tcpdump logs showing them the bogus packets (oh, by the way, the first thing win95 TCP does is send out an arp packet asking for its own Ethernet address. That's right: "arp: who is win95, tell win95"). I have not heard back from them.

[Moderator's addendum: the arp is a way of avoiding duplicate IP addresses. I think this is a Good Thing. As of October 1, 1995, Nick had still not heard back from Microsoft, the NE4100 was still on the Hardware Compatibility List, and the MS technical support lines were unaware of the problem.]

A Windows 95 computer running SunSoft's PC-NFS version 5.x and the Microsoft Client for Microsoft Networks may not be able to see shared resources on a PC-NFS server or an SMB server running the NetBEUI protocol.

This problem occurs because of a conflict between the NDISHLP.SYS driver used by VREDIR and the PCNFS.SYS driver supplied by SunSoft for their PC-NFS client. The conflict causes network packets to be forwarded incorrectly, so no packets are broadcast on the network.

This problem affects only certain PCMCIA and Cabletron network adapters. The following network adapters are known to exhibit this behavior:
