We added a secondary domain controller to our domain that is a Server 2008 R2 std.  There are 3 domains in the forest.  Our main location, consists of 2 Server 2003 DCs and 1 Server 2008 DC.   The 2k3 servers in are replicating with and but the 2008 server cannot communicate with Domain2 and Domain3 on the domain level.  I am able to ping the DC's at the 2nd and 3rd locations from the 2008 server.

If I try to view the other domains from the 2k8 server in Group Policy Management or Active Directory Users and Computers, I am prompted with the error "the domain could not be found because: the server is not operational" or "the specified domain either does not exist or cannot be contacted."  

The DCs at Domain2 and Domain3 seem to have no problem communicating with the 2k8 in Domain1.  I ran repadmin to check for replication errors and the only errors are when 2k8 Server tries to replicate to DC's in domain2 and domain3.  The DCs in domain2 and domain3 are both 2k8 servers.  I have tried turning off the firewall completely do see if that was part of the problem and there were no changes in the issue.   I have also checked DNS info and can't seem to find the issue.

Thanks for your assistance.
