We have a domain controller located in a remote location (A) with ip scheme xxx.xxx.1.xxx. We can join a computer to the domain in location (B) with ip scheme xxx.xxx.2.xxx because we have setup a hardware vpn tunnel to location (A). When we move the computer to a new location (C) with ip scheme xxx.xxx.3.xxx that also has a hardware vpn to location (A) we get the "Trust relationship has failed..." error. In summation:
A to B = Join Domain
A to C = Trust relationship error
The only way for us to get around this error is to disjoin and rejoin the domain from the (C) location.
What is the reason for this, and how can I make it so that I don't get this error from any location regardless of when the computer was joined to the domain originally?
