Hi I have recently added a new Win 2008R2 domain controller to an existing 2003 domain. Before promoting the new 2008 DC i had ran adprep /forestprep and /domainprep on the DC which holds the FSMO in the same domain. I then added the new 2008 server to the existing forest and domain. The issue I am encountering is that the 2008R2 server is not finishing promotion and able to become a Global Catalog. There is another 2003 DC in a different domain that is having replication issues and I am thinking this is the cause.
Should I have run adprep on this DC as well?
The replication errors on the DC in "domain2" result in "Logon Failure: The target account name is incorrect." errors. On the DC in "domain1" replication errors result in a "Schema Mismatch".
Any help would be appreciated as my AD knowledge is limited. Thanks.
