I performed the following steps:
- Created a new installation of server 2003 (std)
- Set it up as a domain controller with DNS, WINS etc.,
- Created a two-way trust between it and an already existing w2k domain with domain-wide authentication (This was created from the w2k3 domain, if that's useful)
All appeared to be ok until after about 24 hrs the trust broke down, but only in one direction (w2k domain could not connect to w2k3). The other direction appears to be working fine.
The error from the w2k DC when I try to verify the trust is: Information from the primary domain controller for the domain w2k3.loc cannot be obtained because: The RPC server is unavailable. Make sure that the PDC is operating properly and then try again.
The error from the w2k3 DC when I try to validate the trust is: Windows cannot find a domain controller for the w2k.loc domain. Verify that a DC is available and then try again.
