In my entire network there are around 25 clients. All are working fine except two. They do not allow me to connect through remote desktop. I had tried to configured the settings a number of time but still it fails. I am using telnet command but somehow it looks the two systems are not responding. All the clients are having a common hardware configuration. I had checked Remote Desktop under terminal services but still it fails to work. I think the firewall is blocking. So I need help here to forward a port. I am going to use 3389 on it. When I try to add the port I am getting a message that cannot use the port.
