SVHost legitimately wishes server rights, and is ok, as is the applications layer gateway, but i'd draw the line at NTKernal. There should be no reason why it should request export / server rights. Your Generic Hosts Processes may also request server rights, which should be granted.
The only one I adamantly refuse to give server rights to is Explorer, I tend to get very paranoid, especially when I Neotraced the given address as going straight back to your mate B.Gates!!!!
(My argument is that I will contact Microsoft when I want, NOT when XP thinks I want.
