On my NT4 domain, I've just put a group policy created with Poledit on the domain controller. Now I'm finding seemingly random users have lost all of their start menu icons. It appears that any icons in the all users directory don't show up anymore. Also, when you right click on Start Menu, you no longer have the option to 'Open All Users'
The policy defined contained the following:
Default User - Nothing defined
Default Computer - Nothing defined
SomeSpecificUser - Horribly restricted
The restrictions for SomeSpecificUser worked properly, but I can't determine why these seemingly unrelated changes are taking place on a random selection of users.
