A Windows 2003 server is in a remote office connecting over a separate Cisco hardware based VPN on a PIX through an ADSL circuit.   After working fine for months, all of the sudden the server has communication problems in finding the domain across the WAN and authenticating.  The result is that it cannot connect to any device outside of the local subnet and in turn, this server cannot be accessed remotely in any way outside of the local subnet (ping, RD, file share, etc).   It is possible to login locally to the server , but domain based login is not possible.  Rebooting has no effect and repowering other devices has no effect.  This server can communicate with other devices at the remote office on the same LAN and other devices at the remote office can communicate successfully with either this local server, to the internet or or across the vpn without a problem and there are no errors logged on the ipsec VPN.   It appears as if policies have locked down the server from anything outside of its 192.168.91.0 subnet because it can't connect to the domain.

I've looked at this ms kb:
Cannot connect to domain controller and cannot apply Group Policy with Gigabit Ethernet devices
http://support.microsoft.com/kb/326152/en-us  

but this is a 10/100 switch and NIC and shouldn't have anything to do with a Gigabit Ethernet device.

==============================
This kb has more promise, How to force Kerberos to use TCP instead of UDP in Windows Server 2003, in Windows XP, and in Windows 2000
http://support.microsoft.com/kb/244474

but why would this occur all of the sudden?  I may be be able to adjust the vpn settings not to fragment instead.
==============================

Any advice?

this is the event id:

sk_raja_raja, adding the NetBT registry entry had no effect.  

I tried updating the Intel network drivers from 2005 drivers to the latest 2007 drivers.  Its an older Dell server using an Intel Pro/100 S Server Adapter but also has a 2nd disabled Intel Pro/100 Network Connection.   The installation automatically re-enabled the 2nd NIC card and by default it was set to DHCP.  The 2nd NIC retrieved a DHCP address from its own server and I was briefly able to gain outside network access to the server for a brief period apparently with that 2nd NIC card.  However, I changed the 2nd NIC IP to a static IP and it immediately stopped working again.  I changed back to DHCP and it did not work immediately, but coming back to it to do further troubleshooting about 60 minutes later, it did work.  

Not only that but the primary adapter is now working.   Since I can't have 2 adapters with the same NetBios name forever, I'll need to resolve by disabling NetBeui on one.  I'm waiting to reboot the server to see if it still works first, then make that change.

Any idea what's happening here?

Possible easy solution that worked for me...
In the DHCP config in our firewall (end point of the vpn) we added
dchpd wins xxx.xxx.xxx.xxx
where the ip was the ip address of our dns server.
We are NOT running wins on the DC but upon reboot of the workstation all the errors went away.
We confirmed this on another customers network and it worked the same way.
Not quite sure why but it works.
