Corrupted AD in Small Business Server 2011 - SBS 2011

Running SBS 2011 and using the supplied backup solution.

I fouled up a RODC and corrupted my AD (no GP, SYSVOL, etc.).  Appears that my best bet is to do a system state restore but this isn't an area I'm familiar with.

If this is the best bet, I need some help on how to perform this on a VM in Hyper-V.

Also asked another question about problems loading the backups during a system restore.

Thanks.

If the SYSVOL and GPO are missing on RODC then yoou have other way to rebuild SYSVOL tree, That does not indicate that the AD is corrupted.

How did you indefied that AD is corrupted? Pleas provide us more info about you setup, DC's, backup strategy etc.. to help you better.

Regards,
Abhijit.

RODC was on a VM that was deleted.  When I tried to create another VM and attach the disk, it didn't like it (different ID number).  I then made it worse by doing a DCPROMO on it and trying to repromote it (lost all the info).

Essentially, when the RODC VM was deleted, I lost access to the GPO and all SYSVOL info.  The SBS server no longer was the PDC and DCPROMO was no help.

I've since performed a system state restore using a guide I found on Google and all appears to be working correctly.

If there was something I could have done differently, I'd still like to know.

Way to recover your DC:
1) Demote and re-promote the server but its valid in multiple DC environment.
2) System state restore-- both single plus multi DC environment.
3) Restoring a Domain Controller Through Re-installation --Single DC and you do not have backup .

Also I would suggest to run DCDIAG, repadmin and check event viewer to confirm the everything is place.
