Went to a client recently to install a new Windows 2012 server to replace the old Windows 2003 domain controller that is starting to fail. Once I added the new 2012 server to the domain I started adding roles. When trying to promote it to a domain controller I get an error that it needs to communicate with the schema master. It appears that the schema was never moved over from an old Windows 2000 server to the 2003 DC and the Windows 2000 server is no longer available.
Additional, if I go in to look at DCs I show the old 2000 server and the 2003 server which shows both as DCs.
Is there a way to get past the schema error and replace the Windows 2003 server?
