We have a single label AD domain with one Exchange 2003 server. We want to get to Exchange 2010. We went through the process of the domain rename operation yesterday using the 2003 rendom tools on a 2003 control station and it does not appear to have worked.
2003 functional level
2 - 2003 domain controllers
2 - 2012 R2 domain controllers
1 - 2003 Exchange server
All clients are WinXP or Win7
Domain name is abcde and we want to get to abcde.local
The NetBIOS name can remain the same.
LDAP lookups still work with old domain naming convention but not with the new one.
We are considering restoring the system state on all domain controllers to before we started.
Any help or a step by step would be greatly appreciated. There has got to be an easier way.
