Remote Desktop Not Working

Hello everyone. I am not able to work on Remote Desktop. It is not showing any specific error, but somehow I am not able to connect it! Can anyone help me to solve this issue? Any kind of solution would be highly appreciated.

After posting here, I searched about this issue online and found some articles like this one. Then I tweaked the Registry for the first time, and my issue somehow got resolved. I am very happy now that I have solved this problem myself.
