Establishing a trust relationship with AD
A domain trust error is driving me crazy! I have two Active Directory Windows 2000 domains (the domain controllers are running Windows 2000 server with SP3): Domain A and Domain B.
I am trying to establish a trust relationship using the "Active Directory Domains and Trusts," but each time I try to add Domain A as a trusted domain by Domain B, I receive the following error:
"The DomainName domain cannot be contacted. If this domain is a Windows domain, the trust cannot be set up until the domain is contacted. Click Cancel and try again later. If this is an interoperable non-Windows Kerberos realm and you want to set up this side of the trust, click OK."
Have you checked to see that both of these systems can resolve their names properly via DNS? This is the most common problem. You can run NETDIAG.exe and DCDIAG.exe on both of the servers. Check the results and resolve any of the problems that you encounter. Also, if there are any firewalls between them, you will need to make sure that the policy allows all of the traffic between the two bi-directionally.
