Do not install Patch KB974571 if you are running OCS!

I just got this warning from a discussion on TechNet about Patch KB974571 released on Tuesday (10/13/09). If you are running OCS (Office Communication Server), DO NOT INSTALL THIS PATCH!!. If you installed it, and have any problems, uninstall it.
