I have to agree here. In my experience of looking at trashed Active Directories, the system file and folder structure is still there, but it's typically one or more components which are corrupt.Quote:

Your Anti-Virus application should still be in Add/Remove Programs, which would also show the file/folder structure has been deleted. Of course the other possibility is malware, but it's fairly rare on a server due to its more 'locked down' configuration in 2003/2008 Server.
