I have scripted DrvDspy.bat to alter the Share Name on 'Computer Name (Comment Text) (Drive Letter:)' sequence that My Computer uses to display mapped drive letters in Windows XP Service Pack 2 and greater.

The syntax for using DrvDspy.bat is:

DrvDspy Comment Drive \[LCL|ALL\]

Where:

Comment  A 0 will display Share Name on 'Comment Text (Computer Name) (Drive Letter:)'
         A 1 will display Share Name on 'Computer Name (Comment Text) (Drive Letter:)'

Drive    A 1 causes the (Drive Letter:) to be displayed first for mapped drives.
         A 2 causes the (Drive Letter:) to be hidden.
         A 4 causes the (Drive Letter:) to be displayed first for all drives.

If no third parameter is provided, DrvDspy.bat configures the Comment and Drive settings for the current user.

If LCL is provided, DrvDspy.bat configures the Comment and Drive settings for all users of the local computer.

If ALL is provided, DrvDspy.bat configures the Comment and Drive settings for all users of all Windows XP computers in the current domain.

NOTE: If a user has used Windows Explorer during their current session, a log off and log on, or a restart, is required for these setting to become effective.

NOTE: If the ALL parameter is specified, NETDOM.EXE from the Support Tools, on the CD-ROM, must be installed on the computer that runs DrvDspy.bat.

NOTE: DrvDspy.bat should be run from Windows XP or Windows Server 2003. It can be run from Windows 2000 with the ALL parameter if the Windows 2000 Support Tools are installed.

NOTE: See How can I rename a mapped drive?

DrvDspy.bat contains:
