I have a computer group that just wont delete. I have tried from the host as well as my workstation. The snapin times out, clicking cancel to let it continue and still will not finish. This group has many updates approved for it though the're no more computers targeting the group. I ran a server clean up thinking that might be the cause and get the same results. It doesn't hurt to leave it but it is no longer of use and wish to get rid of it. As some administrators may get confused to why it is even there any longer.

may be there is a problem in your user permission. !
