We saw that too.
During a meeting discussing the results of testing, it was brought up that NT4 servers with anything less than service pack 6a showed these symptoms. I don't remember any other breakage found. As the instructions for the patch stress having the latest service pack, I'm not sure I'd class this as 'breakage'. I haven't read the bugtrak thread though so there may well be other things I haven't heard of.

Because it is easier to give someone the finger than it is to give them a helping hand.
