Summarize the idea: test the server itself first. Is whether the native mstsc can open the interface, and then enter the native IP, see the error message prompted to determine the problem, unable to connect, it means that the service is not enabled. If you judge that the remote service is normal, find the machine in the local area network and Mstsc it remotely. If there is an unreachable error, check to see if the 2008 firewall is blocking the service, whether it is a third party or built-in. Finally, it can be judged that the remote service is dead, and remote Desktop Authorization (RD Authorization) needs to be installed, but there is a charge to install the service. The link to the RD service installation document is: http://www.jb51.net/os/windows/win2008/134751.html

Note:

1. Check whether remote port 3389 is enabled or change the remote port number, and check it with netstat-an.

2. Change the remote port: in the start-run menu, enter regedit, enter the registry editor, and follow the previous path to enter the modified port HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Control\ Terminal Server\ WinStations\ RDP-Tcp.

Find the "PortNumber" below and display it in decimal mode. The default is 3389, which is changed to any available port. Please note that after the modification here, the modification has not been successful, and the other location of the registry file must be modified accordingly, the path is

HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Terminal Server\ Wds\ rdpwd\ Tds\ tcp

Find the PortNumber below, display it in decimal mode, and make changes.

At this point, you have successfully modified the registry. It is worth reminding that in the advanced properties of the local connection of the network card, in the TCP/IP filter, you must open a new remote port number, otherwise you cannot operate remotely either. Restart the computer and you can connect through the new remote port number.

Under windows 2008, port 3389 of the firewall must be modified, otherwise it still cannot be connected. Modify the firewall to add the newly modified port entry rules, modify the method document link: http://www.jb51.net/article/93431.htm
