IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry



SYMPTOMS
If you disconnect and then reconnect to a different share by using the same drive letter after you map a network drive by letter in Windows Explorer, the share label displays the previous share name in Windows Explorer.

Note that the contents that are displayed are correct for the remote drive, but the label is incorrect.



CAUSE
This behavior can occur if the Windows Explorer DesktopProcess registry value is set to 1.



RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this behavior, delete the DesktopProcess value from the following registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer



MORE INFORMATION
Problems when you use the DesktopProcess registry value are not supported by Microsoft.

Note also that running EXPLORER on RunAs is not supported. This behavior is by design of EXPLORER.

Steps to Reproduce the Behavior
 Add the following registry key as a REG_DWORD value with a hex value of 1:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\DesktopProcess

 Use Windows Explorer to map share A to a drive letter. Disconnect the share, and then map share B to the same drive letter that you used in step 1.

The share label displays as share A even though you are connected to share B.
