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

With 2003 Server this easily done with Conditional Forwarding where the
DNS server on one side, forward all requests for the "other domain" to the
DNS server having that zone.

You may also require NetBIOS to resolve (since EXTERNAL trusts were
designed to work for NT domains) so this will include a practical
requirement
for (a replicated set of) WINS Server(s) with every computer, especially
DCs, as WINS Clients.

I do have conditional forwarding in place, the thing is if i dont add domainA.local to the host files it wont ping the domain A even if forwarding to the dns zone is pointing to domain b to resolve it.

I did have this working the other day, but got the error RPC is unable to contact domain for the SC, so i started again but could not get pass the wizard as i got the above message its very strange.

Thanks,

Thomas
