Reference:

Issue appears to be with login scripts and 2003 and possibly 2008.

Steps

  • Remove login script from user's AD account - May take a bit to propagate (~10-15 minutes)
  • Delete all mapped drives
  • Regedit - Delete any residuals:
  • Computer\HKEY_CURRENT_USER\Network\Z or your drive letter, I deleted Z.
  • Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Map Network Drive MRU and delete the entry, (a, b, etc), for your drive.
  • Reboot to ensure drives don't remap
  • Upgrade desktop to 2004
  • Manually map network drives
  • For MF-BACKUP (2003) (R and Z drives) do the following
  • Regedit
  • [HKEY_CURRENT_USER\Network\r] and [HKEY_CURRENT_USER\Network\Z]
  • For each: "ProviderFlags" (32 bit d-word / hex value 1)
  • Reboot and test
