Dos命令来恢复远程终端连接。附上远程端口开启的命令：

echo Windows Registry Editor Version 5.00>>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server]>>3389.reg
echo "fDenyTSConnections"=dword:00000000>>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp]>>3389.reg
echo "PortNumber"=dword:00000d3e>>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]>>3389.reg
echo "PortNumber"=dword:00000d3e>>3389.reg
regedit /s 3389.reg
del 3389.reg

还提供一个方法，修改注册表开启，什么版本的都适用的，且不会重启。附上命令：

reg delete "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /F
reg add     "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fDenyTSConnections /t REG_DWORD /d 0

Cmd、Dos 下开 3389：

echo Windows Registry Editor Version 5.00 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\netcache] >>3389.reg
echo "Enabled"="0" >>3389.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] >>3389.reg
echo "ShutdownWithoutLogon"="0" >>3389.reg
echo [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer] >>3389.reg
echo "EnableAdminTSRemote"=dword:00000001 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server] >>3389.reg
echo "TSEnabled"=dword:00000001 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermDD] >>3389.reg
echo "Start"=dword:00000002 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService] >>3389.reg
echo "Start"=dword:00000002 >>3389.reg
echo [HKEY_USERS\.DEFAULT\Keyboard Layout\Toggle] >>3389.reg
echo "Hotkey"="1" >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp] >>3389.reg
echo "ortNumber"=dword:00000D3D >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp] >>3389.reg
echo "ortNumber"=dword:00000D3D >>3389.reg

把这些ECHO代码到CMDSHELL下贴粘就可以生成3389.reg文件，接着regedit /s 3389.reg导入注册表：

echo Windows Registry Editor Version 5.00 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server] >>3389.reg
echo "fDenyTSConnections"=dword:00000000 >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp] >>3389.reg
echo "ortNumber"=dword:00000D3D >>3389.reg
echo [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp] >>3389.reg
echo "PortNumber"=dword:00000D3D >>3389.reg

    把这些ECHO代码到CMDSHELL下贴粘就可以生成3389.reg文件，接着regedit /s 3389.reg导入注册表。
