Mostly yeah. But I had a problem before to delete a map. The reason was
that the OWNER was not the administrator, witch is a deffualt, it was the user I deleted, so guess if it took me weeks to figure it out to unhook it. Well it can be so if you restrict a folder, then delete the user and forgot to undo it. :P
The thing is to login in with an administrator and signrights. It is neede a pro skills to get it to work. I am a pro, but I not the best man to explain things, so sorry can help you. A tip is to do some research in Microsoft support page.
