All, I've been biggling around teh interwebs, and crusing through the faqs and manuals, and don't see how to block this protocol. Given the 0day (http://laws.qualys.com/2010/06/new-0-day-for-windows-xp2003.html) that has been released for XP and Win2k3, it seems prudent to do something about it, but I just can't figure out how. Anyone have a pointer for me? Thanks, Kurt
