found that the remote connection can not be connected, and then looked at the next 3389 is normal to open, and the Terminal Services service is also open, and later looked at the server other server situation, saw a firewall with Windows (Windows firewall/ Internet Connection Sharing (ICS) service.
So in PR under the use of net stop sharedaccess command after shutting down the firewall found still not normal connection, and then see the server has opened the IPSec Services service.
But now execute the command under PR you cannot stop with a command such as net stop IPSEC services, if we can execute net stop IPSec Services in the case of MSSQL rights This command to stop the IP policy service.
Because the PR right we entered the command to be enclosed in quotes, so can not use the above method to stop, in fact, in the CMD stop a service we need to use the "net stop service Name" way to stop, such as the Windows default Firewall service name is "SharedAccess", And what we see with net start is his display name, "Windows firewall/internet Connection Sharing (ICS)," so we're going to stop Terminal Services, You need to know the real service name.
