I posted this elsewhere but I'm having trouble getting an answer. an update (KB907747) for IMF will not install. It gets three quarters through the install and just sits there endlessly, but still shows as running in task mgr. After hard reset of the server I can see this UD in add/remove, but the update is still also waiting to be installed in task bar icon. If I remove in add/remove I believe I would be taking IMF back with no updates at all if I am understanding this correctly. How do i troubleshoot this?

Try re-installing exchange SP2
