I have two Windows Server 2003 domain controllers in two separate domains
(one per domain). Both domains are at the Windows Server 2003 functional
level. Both have DNS installed for their own domains are are secondary DNS
servers for each other.
On SERVER1 in DOMAIN1, when I go into AD Domains and Trusts and try to
establish a trust to the other domain, when I type in the DNS name (or the
NetBIOS), I get the following message:
New Trust Wizard
The name you specified is not a valid Windows domain name. Is the specified
name a Kerberos V5 realm?
Then you can select the "appropriate" trust type: either "Realm Trust" or
"Trust with a Windows domain"
I've tried both and neither work.
