In tip 4600, I explained how Windows 2000 and Windows XP stores the information about a renamed mapped drive.

If you wish to map and rename in a logon script, use RenUse.bat. The syntax is:

RenUse "New Name" DriveLetter: \\ComputerName\ShareName \[Options\]

where:

"New Name"	will display as New Name (DriveLetter:).
DriveLetter:	is the drive letter you are mapping. Previous mappings will be replaced.
\\ComputerName\ShareName	is the standard net use syntax.
\[Options\]	are any additional net use switches that you want.

Processing and Requirements

Windows NT, Windows 9X, Windows ME

"New Name" is ignored, even though it is a required parameter.

Any previous DriveLetter: mapping is deleted and DriveLetter: is mapped to the \\ComputerName\ShareName \[Options\].

Windows 2000

The Windows 2000 Resource Kit REG.EXE program is required for writing New Name to the registry.

The conversion of New Name to Unicode takes a few seconds, more if New Name is long.

Windows XP

REG.EXE is installed when Windows XP is installed.

Windows 2000 and Windows XP

The client must have permission to write their own registry hive.

Any previous DriveLetter: mapping is deleted and DriveLetter: is mapped to the \\ComputerName\ShareName \[Options\].

The following characters may NOT be used in New Name:

" % & : ;  ^ | ~

RenUse.bat contains:
