We upgraded our NT 4 domain to an AD domain with the primary controller
being a Windows 2003 Server. I had one policy set for automatic
updates and I need to take it out so I can install the new Windows
Update Server program on a different machine.

I am logged in as Administrator on the 2003 box. If I go to
Start->Programs->Administrative Tools->Domain Security Policy, it tells
me that the Network path can not be found and the editor comes up blank
if I click OK.
