解决win server出现远程端口33890被占用进不去的问题：

通过vnc进入服务器后：

reg add "HKLM\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v PortNumber /t REG_DWORD /d 53389 /f
netsh advfirewall firewall add rule name="RDP_Custom" dir=in action=allow protocol=TCP localport=53389
net stop TermService && net start TermService
