A red "X" appears in the icon for a mapped network drive in Windows Vista, even though you can successfully access the drive


In Windows Vista, a red "X" appears in the icon for a mapped network drive in Folders area of Windows Explorer. However, in the details pane, a green pipe appears in the icon for the same drive. Because you can successfully access the network drive, you expect the icon to appear as a green pipe in both areas.

This problem may occur if the following conditions are true:
  • The network drive is mapped by using user credentials that differ from the credentials that were used to log on to Windows Vista.
  • You do not select the Remember my password option when you map the network drive.
  • You log off the computer. After you log on again, you double-click the network drive and then enter the credentials to reconnect to the drive.
After you restart Windows Explorer, the problem does not occur.


This problem occurs because of an error in the Shell32.dll file. When the mapped network drive connects to the computer, the Shell32.dll file updates the network drive icon only in the details pane of Windows Explorer. An event is not generated to change the icon in the Folders area.
