You might at least rummage around in the AD tombstoned deleted trash to see if the records actually were deleted or if something
more bizarre is happening.

I could not muster great deal of confidence in a configuration where AD objects self-destruct of their own volition. I can't think
of any policy settings that would cause this, and I have to believe this is a replication issue.
Since this seems to apply only to a subset of workstations you might try reloading the O/S by hand on one of those to see if it is
something in the workstation config that is triggering the problem.
