I recently changed over our old login script that mapped network drives over to group policy preference drive maps. Worked through a few issues at first, but appears to be working fine for all of our users. However, one issue that I'm having on one Windows 7 workstation, is that it's mapping all of the drives it's supposed to, but it's also mapping one of the network drives multiple times. The longer his computer goes unrestarted, the more copies of this drive get mapped. It starts with the actual drive letter, S. Then you start to see Z, Y, X, etc starting to appear. One day he had at least 10 copies of this drive appear.
Anyone know how to troubleshoot this?
