I set up a new computer with windows server 2008 and workstation windows 7 professional. The server been in place. There are other Windows 7 workstation allowing Remote Desktop. I have configure all the settings. I have allowed the computer to be accessed - allow access from computers running any version of remote desktop. I am using another port besides the default 3389. I have changed the settings in the registry. I have created a rule in the firewall for a port - using port 3390. We are using other ports with the same ip address and they are working fine. I get the error that this computer cant connect to the remote computer. I even disable the firewall. I went to the site www.canyouseeme.org. It shows the port is open and not blocked by my ISP provider. What is left to check?? I have matched the configuration with the other Windows 7 workstation.
