[Samba] Is the net rpc vampire at all destructive to a NT4 PD C?

"net rpc vampire ..." does NOT set the SAM or SECURITY hives of the
registry to "readable", which is what renders the PDC non-operable.

"net rpc vampire ..." is safe to use as many times as it takes to get
comfortable with the process.  I did it my self when I was converting
our "labs" NT4 domain to Samba.
