I setup a server running software distribution through the group policy's unfortunately the AD corrupted and lost all of the AD however all the data was intact. Ive just rebuilt the server AD and group policy's from note. When i disconnected and rejoined the computers all the links to the old software distribution were still there and all the links started up but failed because the software was no longer there. Is there a way of removing this data from the local machine I've found a folder called software distribution within the windows folder and assuming it has something to do with that. I just need to be sure or if there are any other ways to cure the system.
