cannot find \\ServerName

Something happened in the last few days. I have a Windows 2K Active Dir Native Mode network. I have Windows 95/98/2000/XP clients. I have 5 Domain Controllers. My PDC Emulator DC (ProblemServer) that also holds Exchange 5.5 won't athenticate Widnows 95/98 clients. In fact, if the NETLOGON service is running on that DC all Windows 95/98 machines get "The domain password you supplied is not correct, or access to your logon server has been denied." If I stop the NETLOGON service the Windows 95/98 clients logon find (With the logon script and everything). Windows 2000/XP client always logon fine. If I go Start > Run, \\ProblemServer from Windows 9x I get "Cannot find \\ProblemServer". Windows 2000/XP are fine. They can go Start > Run \\ProblemServer and access shared folders. All other servers I can access from Windows 9x by going start > run \\OtherServer. I can ping for Windows 9x to ProblemServer. The only thing I can think that I added to that server this week is "Exchange 5.5 CDO Patch 2657.55" to solve an OWA problem. Any ideas? How do I log logon problems? Monitor logon problems?

All of your DCs are W2K and above?
You're not running native IP mode now, are you?

We have been in native mode for over a year with no
problem. All DC's are Win 2k. Evrything has been great
until 4 days ago. Last time this happened I upgraded the
NIC driver on one of the servers and the problem went
away. I upgraded everything and nothing changed.
 
you should be in mixed mode

Jeff...

I think you misunderstood my question. Native/Mixed mode is different than
native IP/NetBIOS over TCP/IP mode. Windows OS, prior to W2K, can only use
NetBIOS over TCP/IP, even though it says TCP/IP. Native IP is what *nix
uses unless they're running SAMBA.

Native/Mixed mode relates to the make up of your DCs (domain controllers).
Mixed mode means you have W2K/3 and NT4 DCs. Native Mode means they're all
W2K/3. Both of these can serve Win9x/ME/NT/W2K/XP clients. In Native IP
mode, ONLY W2K and above clients can communicate with the servers.

This is why I made sure I said Native IP mode and not just Native mode.

RE: your response... Do you recall, last time this happened, if you had
upgraded or installed something that required you also upgrade a NIC driver?
Servers do not normally just stop working unless something has changed
somewhere that requires and update unless it has to do with capacity, i.e.
disk space, traffic, etc.

HTH...

Oh, I see. I added an update to the OWA because it kept
crashing, I would reboot the server, and it would be fine
for a day. I added:

http://www.microsoft.com/downloads/details.aspx?
FamilyId=B106C749-71F8-44CC-86CF-
AB5CDA169127&displaylang=en

Then people with Win 9x started complaining. The wierd
thing is them (Win 9x not Win 2k)not being able to go
Start > Run \\ServerName. They can do that to any other
server but that. It is the PDC emulator. The patch I
installed doesn't come with a uninstall. Help. Last
time this happened I updated the NIC driver (on the
server) and it worked. Is there like a sniffer tool that
is good to see what is happening? How about NetDiag?
