Cannot run Group Policy editor anymore

[Guest]

I'm not sure what just happened, but I am no longer able to run
gpedit.msc on my Windows XP SP2 laptop. When I try to run it, I get a
"You do not have permission to perform this operation. Access is
denied." error. This happens with 2 different Administrative users.
I even rebooted and that didn't help.

The only thing unusual that I did tonight is that I added a Deny
everything permission for the Users group to the C:\WINDOWS
\system32\GroupPolicy\User folder. But I have removed that permission
now, and I still get the error message.

Any idea what's wrong?

Lesson # one: do not **** with areas you do not know.
Lesson # two: always backup !
Did you try system restore point?

Reboot. Sometimes this is required after adjusting permissions.

Well I do know that area. And I was doing something described in a
microsoft KB article.

Lesson # two: always backup !

I added and then removed a permission, nothing to back up!

Did you try system restore point?

Thanks for the tip, that worked (rebooting did not work). Kinda
disturbing though, as the adding and removing of the permission should
not have caused the problem. Better not try this on Windows 2000,
which doesn't have System Restore!
