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.
