Check your domain controllers event logs for authentication failures. I had
a customer with a similar problem. It's been a while, but I think it was the
result of a some process that was trying to authenticate and failing so many
times that it hung RPC. Might have had to do with a trust. Just found my
field notes from the issue and there might be some helpful information there
- I'll send them to you off-list.
