I am in the process of demoting a 2003r2 DC. I have set up a 2008r2 Server, set it up as a DC and moved all the roles over. Now I am ready to demote the older DC. When I run a dcpromo I am getting the error
" The Operation failed because: Active Directory could not transfer the remaining data in directory partition CN=Schema,CN=Configuration,DC=[Domain],DC=com to domain controller server2008.domain.com
The RPC Server is unavailble"
I am in need of some insight. According to AD, the 2008 server is the primary server for all the roles. I can confirm this from both server. Any help is appreciated.
