Server creating duplicate drives of itself every couple days

Corcent used Ask the Experts™
I have a client where it appears every few days their server creates an exact copy of it's drive on the office computers. So, for example, the server's drive everybody uses is S:  then after a few days the server will make a copy of it and the users will see an S: and an F:. Both are exact copies of each other. Both drives have all the files and the files have no issues opening. When saving in the usual S: the file instantly is also copied to the F:. Deleting the F: has no impact on the S: and the main drive continues to operate as normal until a few days later then we'll see a G: that is a copy of the S: again.

Any thoughts?

Sounds like an issue with either group policy preferences or a login script. Go through both and verify which one is trying to map the drive and which one is deleting it.

Run that, check the GPP

Then go to your netlogon and check the scripts in there.

Look in Scheduled Tasks and see if there is something running about the time that the duplicate shows up.

DFS Namespace created across all of the systems?
I ended up figuring it out. The user had multiple duplicate shortcuts on another computer in the office that pointed to other duplicated shortcuts on the server. Deleting the shortcut from one place wouldn't fix as when the user clicked to open the shortcut it would recreate the duplicate. I had to delete the shortcuts on both computers. Then the duplicates stopped re-creating themselves.
