AD Migration (error 8250)

[ppantelis]

Hi!
My aim is to raise a new AD on a new DC in a new forest and then, migrate the OUs from the old AD to the new one.
I have until now managed to establish a (validated) trust relationship between the 2 DCs.
However, when i try to use the ADMT (for testing reasons, i want to transfer a user with source=oldDC & target=newDC), i receive the error "server is not operational, error=8250".
I read a lot of articles saying that i must define forwarders on both DNSs. I' ve done so.
Then i read i must create secondary forward lookup zones on both DNSs, but not successfully: "Zone not loaded by DNS Server" (

http://support.microsoft.com/kb/816518).

I know that this is a DNS issue, but i cannot overcome it...
Any ideas?
Thanks!!!

Have the SRV records been created for these domain controllers . Try using the DCDIAG and DNSLINT tools in order to establish possible issues.

Thanks for answering!
SRV records exist and are OK.
I 've also run DCDIAG (this one I had run it from the very beginning) and DNSLINT tools, all successfully...
