This is very similar to a situation I experienced the other day. It's all
in a thread over on the Exchange list ("Exchange 2010 AD Topology service
weirdness"). Unfortunately, I don't have a resolution for you. In
addition to the Exchange issue, I saw exactly the same thing with slow
logons, slow group policy processing, odd ping behavior, etc.
The only thing I could find that was related to what was going on (and only
partially at that) was the kb article at
http://support.microsoft.com/kb/2408181.
Good luck. I hope you get this resolved.
