At the end of my wits, I checked my Exchange server at home to compare it to the one at work.
I found the following anomoly:
In the Registry key:
\\HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Netbios
there was only ONE entry on the non-working Exchange 2000 Server, and TWO entries on the working one.
Both had the following DWORD values:
Name - ncacn_nb_tcp0 TYPE - REG_DWORD Data - (0)
The one at home also had the following:
Name - ncacn_nb_tcp1 TYPE - REG_DWORD Data - (1)
Sure enough, I plugged this into the Exchange Server at work and people are able to login just fine.
Hope this helps someone!
