I have a Net Folder server that was used strictly for User Home
Directories. The contents of that volume were migrated to a new
server (OES11 to OES11). I setup a new Net Folder server and pointed
it to the new volume and it works fine. I now want to delete the old
Net Folder server. When I try to delete it, it says that it cannot be
deleted because it is currently being referenced by Net Folders. But
I do not have any Net Folders created that reference it. How do I
delete it?
