DNS Issues during Migration

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I have two Domain Servers (DNS, AD) on the same subnet with different DNS
Names and Domain Names. One is W2K3 named 123.com (10.10.10.5) and one is
W2K abc.com (10.10.10.6). The object is to migrate users and mailboxes from
abc.com to 123.com and then kill off abc.com. Both servers can see the
internet and forward DNS correctly, but niether server can resolve the
other's domain name on the same subnet. This is keeping me from migrating
mailboxes and users between the domains (as the trust fails becasue the names
aren't resolved).

I have tried pointing IP Properties to each other, but they go to the
internet to get resolution. The LMHOST file has each other's addresses. I
have tried adding each of them as 'Hints' and as DNS servers in DNS - nothing
works.

Ideas? TIA.
