dcpromo

When attempting to promote a secondary server to an existing active directory forest I receive the following error message and can no longer continue.

Failed to examine the active directory forest. Value ridMasterDSA.partentDN not found

What can cause this and what can be done to fix it?

Both servers are 2008 running on x64 and can see each other on the network via their names. FYI: The firewall is turned off on both machines so there should be no issue there. Also the server that i'm adding is already a part of the domain. One server is already a domain controller but I want to add a second to it.
