Domain Trusting

Hello All,

I am having big problems setting up a two way trust from domain A to domain B.

I get the error message : The new trust wizard cannot complete because the domain cannot be contacted.

Either the domain does not exist or network problems are preventing connection.

From domain A i can ping domain B
From domain B i am unable to ping A.

Steps taken so far, add host files, lmhosts, zone transfered DNS from domain A to B and B to A.

When i added to host files i was able to ping from Domain B to A.

Also tried FQDN and DNS still nothing, any help would be great.

Also in TCP/IP settings we dont have the IP address of the internal DNS its another address but i do have forwarders in place.

Thanks,

Thomas
