How do I resolve the error "The local device name is already in use."?
Solution 1:
You need to remap the drive.
First:
net use * /delete
Then remap it using net use again:
net use Z: \\server\share /user:username password
Solution 2:
It happened to me when I woke the computer from overnight sleep. I started stopping service after service and it seems that the "Computer Browser" service was at fault in my case. Try:
net stop browser
net start browser
Solution 3:
- Delete the registry key
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2 - Logoff, then logon
If it still does not work, disconnect all mapped drives either from GUI or command line as in the previous post, delete the reg key above, and then log off and log on
Solution 4:
One possibility that I just ran into is that you've added a device to your system that causes other "auto mapped" devices to bump up over the mapped drive.
Say you have M: mapped to a network drive, but you add a new harddrive that then causes all the removable drives (even though they don't have anything inserted into them) to bump up a letter (or two).
Now, suddenly, one of the removable drives is mapped to M:, so your network drive can no longer be mapped to M:, and when you try to remove the mapping, it'll give you a Device already in use error.
Open up "Storage/Disk management" and check ALL the drives for any mapping that might be on top of the drive you want to map.
If there, just remap that drive to something else.
Then you should be able to use net use to attach to your network drive properly.
