Answer : WinNT Server and Trust Relationship

Do you have a WINS server?  If not, you should  consider implementing one.  Otherwise, create an LMHOSTS file with the target server's name and domain name info.  For example, if you're first server is named server1 in domain1 with IP of 192.168.100.1 and you're second server is server2 in domain2 with IP of 192.168.200.1 then server1's LMHOSTS file should read:

192.168.200.1      server2                 #PRE #DOM:domain2
192.168.200.1      "domain2        \0x1b"           #PRE
192.168.200.1      "domain2        \0x1c"           #PRE

Modify accordingly for Server2 to point to server 1 (especially if this needs to be a two-way trust.

We had an experience where our WINS database was corrupt and trusts refused to connect.  After a call to Micro$oft, they told me to add the lines above and that did solve my problem - and we do go through routers.  Incidentally, the lines with quotes must be 20 characters long.  So in the examples above, its "domain1" followed by 8 spaces, followed by "\0x1b" or "\0x1c"
