User accounts being removed from Active Directory automatically.

Did this happen with anyone else:

After installing some security updates from Microsoft on one of our Domain Controllers, user accounts are getting deleted randomly from Active Directory. Some computer accounts are also getting removed but less numbers  than the user accounts. I re-created those accounts but some of them disappeared again. Checked Event Viewer but nothing suspicious there. Only thing I notices that the problem started after installing security updates from Microsoft.

It started on Tuesday 15/12/2009.

Our environment:

PDC: Windows 2003 R2 SP2
BDC: Windows 2000 Server SP4
Exchange 2007 on a seperate server

Thanks in advance.

Is security update is compatible for user a/c data?,  If yes go back using backup and try manual update. Find the stage of error and inform to software vendor for correction. Thanks.

How to check whether security update is compatible or not for user account data?

Is there any way to check Active Directory object additions/deletions logs (it is not in Event Viewer)? OR is it possible to enable logging for Active Directory additions/deletions/modifications?

I have never seen Active Directory delete objects randomly. Certainly not caused by an update from Microsoft. If the update was doing that then it would be well know. I suspect it was a coincidence and something is doing it.
You may well have to take it to Microsoft for resolution though.
