Server will not delete, it is being reference by Net Folders

After removing some Net Folders, I am trying to delete a Net Folder Server but I keep getting the error message:

"The following Net Folder Servers could not be deleted bcause they are currently being referenced by Net Folders."

There are no references in the Net Folders section to this server.

I finally gave up and deleted and recreated the Filer Server from scratch.

Looks good until a few hours later, this same unwanted server appears out of nowhere and it will not let
me delete it.

Very frustrating and a big waste of my time.

Does anybody have a clue as to what is going on?

I am still in the testing phase, so besides myself there are no other users.
