Windows Command Line

Mounting and Using Network Drives

use net use

example:

net use X: \\SERVER\Share

Where X: is the drive letter you wish to map the share to, and \\SERVER\Share is the UNC path to the share. This should make the share visible in My Computer and the command line as well like all other shares mapped through the GUI.

In order to later disconnect the share, you would use

net use X: /delete

if you want to keep this mapping you can add the switch /persistent:yes Also, sometimes when you try to assign to something that is already assigned you may have to first /delete the mapping. This is the case for printers mapped to LPT ports at least, and if you can't seem to get it working, try that.
