cmd查看并开启3389

1.查看是否开启3389 (0表示开启，1表示关闭)

REG QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fDenyTSConnections

2. 查看开启的端口 (16进制的需换算成10进制)

reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v portnumber

3. 开启3389命令

win08使用一下三条命令：
1.
wmic /namespace:\\root\cimv2\terminalservices path win32_terminalservicesetting where (__CLASS != "") call setallowtsconnections 1
2.
wmic /namespace:\\root\cimv2\terminalservices path win32_tsgeneralsetting where (TerminalName ='RDP-Tcp') call setuserauthenticationrequired 1
3.
reg add "HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server" /v fSingleSessionPerUser /t REG_DWORD /d 0 /f

别的版本系统：
win2012通用；win7执行前两条即可。权限需要run as administrator。

win03 winxp 一条命令即可：
wmic path win32_terminalservicesetting where (__CLASS != "") call setallowtsconnections 1
