Reconnect mapped network drives using Windows Command Prompt script

Posted on by Kulvinder Matharu

When booting into Windows, the OS sometimes does not reconnect mapped network drives even though the mapping is configured with the “Reconnect at sign-in” option. This is due with various timing constraints of resources during boot.

Although there are free Third Party software available that can automatically reconnect your mapped network drives, I would rather be able to do this using built-in tools than add more unnecessary software to my system. I’ve therefore written a Command Prompt script using the “net use” command. Not the prettiest of code but it does the job. Tested in Windows 10 Pro 64-bit.

The script was saved as a .CMD batch file which is executed by twice using Task Scheduler at user log on; one in non-admin and the other in admin mode. This allows mapped drives to be visible to those applications running in non-admin and also to those applications running in admin modes.
