File | Disconnect Network Drive
Click Disconnect Network Drive on the File menu to remove network connections.
When you click Disconnect Network Drive, the Disconnect Network Drives dialog box appears. In the Network Drives box, select the connection you want to remove and click OK.
This dialog box works exactly like the corresponding feature of Windows Explorer.
The File | Disconnect Network Drive command affects only the network connections of the computer on which WinDbg is running. If you are using WinDbg as a client in a remote debugging session and you want to change the network connections of the server, you must use a .shell net use command.
For more information about accessing the command shell, see Using Shell Commands.
