I recently had a test install of Exchange 2010 added to my Exchange 2003 environment. After doing testing, I uninstalled Exchange 2010. The uninstall was rather involved, as you have to disable and remove several things for the uninstall to actual continue. After finally address the mailboxes, the uninstall of 2010 seemed to go fine and I renamed the server without issue, leaving my Exchange 2003 server behind. Upon reboot, my Exchange 2003 server was not happy. upon going through the registry and System Manager, I did find some discrepencies from my production enviroment.
Within ADSIedit, I see that there are no subfolders under Active Directory Connectors. There should be 4.
Default ADC Policy
Within System Manager, there is an Exchange Administrative Group that was put there by Exchange 2010 that can't be removed (says that there are objects within it).
My question is if there is a way to recover these missing subfolders? Do I have to reinstall the ADC? I don't really want to have to restore my DCs and then re-add all servers. Luckily, it is a test environment, but it is overhead that I'd like to avoid.
I'm getting several 2114 and 8108 errors.
Thanks for any suggestions.
