Here is what I have.
1 is 2003 running as a DC
1 is 2008 running as a DC and hosts Exchange 2010
I did a dcpromo and removed the 2003 server from AD as a DC. Now Exchange wont start on the 2008 server. I'm getting system errors 7031 7024 and application event ids 2114 2604 2012 5000 and 1121 All are related to Active Directory and services unable to start.
I tried a setup /preparead and it tells me that it cant find the recipient update service.
What a pain. A simple DC removal is now a 10 hour project. Any help is appreciated.
