I have a computer running Windows 7 Enterprise with a network drive mapped to another commuter running Windows XP Professional. The C drive in the computer with XP went bad and the computer was replaced. However I cannot disconnect the mapped drive. If I try to disconnect it using the context menu option in Windows Explorer it brings up a dialog box that says, "This network connection does not exist," and does not disconnect it. I have also tried to disconnect it from the command line: C:\>net use Z: /delete The network connection could not be found. More help is available by typing NET HELPMSG 2250. C:\>net helpmsg 2250 The network connection could not be found. C:\> This problem is very annoying. Please help.

In cmd windows, you can directly type command 'net use' to see the net connection. If the Z: doesn't existed in the list, 'the network connection could not be found' is normal. And you can directly define a new network location to Z:.

It still showed up in the list but would not let me disconnect it. However, it replaced it just fine. Thank you.

once you replace you can delete the mapped drive now..Regards, h9ck3r.

I was experiencing a similar problem on my computer. The root of the issue is that the drives where initially mapped when explorer.exe was started. As you said, after "disconnecting" them they still appeared in My Computer but not "net use". Restarting explorer.exe at this point removed the drives from My Computer.
