ERR2:7711 Unable to retrieve the DNS hostname for the migrated com

[Ully]

ADMT v3.1
Full Message:
Unable to retrieve the DNS hostname for the migrated computer
'<hostname>.<sourcedomain>.local'. The ADSI property cannot be found in the
property cache. (hr=0x8000500d)

This is the error I'm getting when testing a migration of computers. All
machines are running XP SP3. I had to disable the anti-virus to install the
agent. The message is a bit vague about whether the name resolution problem
is in the source or target domain.

I had managed to work out most of the snags we've come across, as this is
the first time I've used ADMT, but there is almost no information about this
error by google or bing and nothing on the Microsoft Help and Support Site.
Any clues? And thinks in advance.

Update:
Just found these two on the computer to be migrated:

The 40961 errors are not the errors related to your DNS hostname query errors.

DNS is specific to each forest. Part of migrating from one domain to another domain in a different forest, is you must setup DNS resolution capabilities between both entities. The easiest is to setup a Conditional Forwarder from domainA.local to domainB.local's DNS server, and vice versa. This way anything in domainA.local can resolve domainB.local's records.

Also, do not use the ISP's DNS server in any machines IP properties. If so, thatwill surely give you errors. Also make sure you do not use the router as a DNS address. Same thing. The router or the ISP have no information about the internal domain names. Setup a Forwarder to the ISP.

I hope that helps.
