OK i am having issues with a GC server. I have a flat forest with 4 GC servers. The local server was installed as a "core" win2k8 box of which i know nothing about. It began having issues replicating that i noticed about a week ago. Its tombstone is sitting at 59 days right now. I started seeing all kinds of issues with trust relationships etc today. I tried various MS solutions to get the kerberos to work and it did not help. So i promoted a member server to a GC. The problem is that this server cannot talk to the existing server to get AD info. How can i point the new GC to another site (flat network) GC to replicate AD info back to the site i am on? I believe that if i simply demote the current GC that is having issues i may lose Exchange and other services tied to the GC..esp since the new GC is not getting replica sets from it.. any ideas?
