Missing Active Directory Connectors

Greetings,

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.

Config CA_<DOMAIN_SERVER>
Default ADC Policy
Public Folders
Users

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.

Installing Exchange 2010 in a domain with Exchange 2003 destroys those connector entries, for the most part. You might be able to re-create them from the Exchange 2003 server, but a 2010 to 2003 rollback isn't exactly something Microsoft supports, so there isn't a lot of documentation out there on how to do it. You could potentially do an AD restore of the attributes from a backup that you took prior to installing Exchange 2010 to get those connectors back in, though. Of course, you have to have backups to do that.

Right.  As this is the test environment, I don't have any backups.  I do see that I can restore via Directory Service Restore Mode or using ADSIedit, but they look messy.  If I'm gonna do that, I'm better off restoring a fresh test enviroment, but ugh.  You are correct on the 2010 documentation.  It is not readily available.  Was just hoping that this was a known issue with a known resolution.

Whoops.  Forgot all about this.  The issue ended up being a corrupted image of my Exchange 2003 server.  Upon re-implementing my previous physical Exhcange 2003 server, I was able to re-establish the relationship with the AD and get it working.  Did take some messing around to clean-up the restored IS store, but it was OK.  Sorry for the delay in closing this.
