How do I find where a network drive is mapped to in Windows 7?

Go to Start » Run, type in cmd and press OK.

In the cmd box, paste the following, then press Enter to run it.

wmic path Win32_LogicalDisk Where DriveType="4" get DeviceID, ProviderName

Doing the above but typing in NET USE instead of copying the above also yields the same result.

In Windows Explorer, you can also switch the view to "Details" and right-click the header to add a column named "Network location":

Helps if the admin has disabled CMD for you (!)

Sometimes the net use or the Win32_LogicalDisk will not show some of the mapped drives, powershell cmd:

gwmi win32_mappedlogicaldisk | select name, providername 

will work then. The corresponding windows cmd is the following:

wmic path win32_mappedlogicaldisk get DeviceID, ProviderName
