Hi All, I'm trying to establish a domain trust between our old domain and our new one before I begin migrating accounts/computers etc. However, I am having a problem when I try to establish the two way forest trust. I get the following error: The attempt to read the names claimed by the specified domain has failed. The operation failed. The error is: There are currently no logon servers available to service the logon request. Both domains are at 2008 R2 functional level. I have configured conditional forwarders on both domains DNS servers. I am able to successfully resolve the FQDN's of domain A from domain B and vice versa so I know the DNS forwarding is taking place. There are no firewalls in the between the domain controllers. They are in fact sitting on the same subnet and can ping each other. The output from nltest is the same on both domains but reversed, if you see what I mean. C:\Users\administrator.EXN>nltest /dsgetdc:domaina.local DC: \\VADsrv3.domaina.local Address: \\192.168.0.15 Dom Guid: 4882f59d-a8dd-41f7-9a0b-3f1ec97eb119 Dom Name: domaina.local Forest Name: domaina.local Dc Site Name: test Our Site Name: test Flags: GC DS LDAP KDC TIMESERV WRITABLE DNS_DC DNS_DOMAIN DNS_FOREST CLO SE_SITE FULL_SECRET WS The command completed successfully Anyone run into this issue before? Thanks

I see no reason that you can't create the trust relationship. Have u restart the DC and try create again?

Try configuring stub zones instead of domain forwarders.
