net use


The NET Command is used to connect to a File/Printer Share as follows:

Join a file share (Drive MAP)

NET USE [driveletter:] \\ComputerName\ShareName /PERSISTENT:YES

NET USE [driveletter:] \\ComputerName\ShareName\folder1\folder2 /PERSISTENT:No

Make all future connections persistent (auto-reconnect at login)

NET USE /Persistent:Yes



Make all future connections non-persistent (reconnect with login script)

NET USE /Persistent:No



Join a file share (Drive MAP) - with a long share name

NET USE [driveletter:] "\\ComputerName\ShareName"

Connect a user to their HOME directory

NET USE [devicename | *] [password | *]] [/HOME]

This requires the users Home server/folder to be defined in ADUC

Join a password protected file share (Drive MAP)

NET USE [driveletter:] \\ComputerName\ShareName[\volume] [password | *] [/USER:[domainname\]username] [/PERSISTENT:No]

In the above command /USER can also be specified as:

[/USER:[dotted domain name\]username]

[/USER:[username@dotted domain name]

In a script, to map a drive and wait until the mapping has completed before continuing:

START /wait NET USE [driveletter:] \\ComputerName\ShareName

This will be a little slower, but ensures that files can be read from the mapped drive.

Join a Printer Share

NET USE [LPTx:] \\ComputerName\printer_share /PERSISTENT:YES

Join a Printer Share - with a "long" share name

NET USE [LPTx:] "\\ComputerName\printer_share"

Disconnect from a share

NET USE [driveletter:] /DELETE

Disconnect from a share and close all resources (undocumented)

NET USE [driveletter:] /DELETE /Y


NET USE H: /Home

NET USE J: \\MainServer\Users\%Username%

NET USE W: \\MainServer\GroupShare /Persistent:No

NET USE \\MainServer\SharedPrinter


NET USE command can map a network printer to an LPT port (for DOS type applications that print to a port.) but this does not add the printer to Control Panel - Printers.

By default all mapped drives have a 15 minute idle session timeout, you can modify this with the NET CONFIG command. In windows XP the explorer icon will change to show this change in status, this behaviour is to improve overall performance.


Windows Scripting Host (VBS/WSH) provides alternative and arguably better commands:



Drive Descriptions

Recent versions of Windows display a drive description for each share, this can be edited in the Explorer GUI. The text is stored in the registry.

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\##ComputerName#ShareName _LabelFromReg=<description of drive mapping> (string REG_SZ)
