windows2003 Remote Desktop has exceeded the maximum number of connections forced logon method

When the remote desktop exceeds the maximum number of connections, you can use the following command to force the login to execute on the command line:

Usage: mstsc/console/v:ip:port | Mstsc/v Ip:port/console
Example: mstsc/console/v:192.168.0.1:3389

If the target host modifies the terminal port, the port is changed to the modified ports.
