I've experienced this exact same problem. Unfortunately, I don't have a fix yet, but I wanted to provide a link to my post at the System Center forum in case anyone posts anything helpful: http://social.technet.microsoft.com/Forums/en-US/configmgrgeneral/thread/79368c27-e7e4-4578-8c8d-a7c40af8c1c3
It's really driving me crazy. Hopefully someone can point us in the right direction.
