I need to set up a duplicate domain, so that I can recover my exchange server on my test environment. The problem I am having is even getting my active directory GC server up. I am restoring it to another make of server, something a lot smaller. It starts up and the DNS works. But when I run the dcdiag.exe util, it comes back with lots of errors, including error 1355, and "the server holding the PDC role is down". I am getting desperate as I have tried 100 different techniques in re-building my server.
