Haven't seen this yet. But if you can provide some logs, it would be
easier to say what could be wrong.

I would suggest, to wait if this was just something that happend once.
If not, then set your log level to 3 (should be enough for a bit more
details, but low enough to prevent flooding your log directory and slow
down the environment).


Btw: PDC is something you're having in an NT4-domain. In an AD, there
are just DCs. And all are equal (byside the 5 FSMO roles). ;-)
