If it says request type out, then the IP address is either wrong, or the computer is not on the same network as you are or the computer is switched off....

What Program are you using to remote desktop the PC??

Also what is the operating system you are using, and the operating system your trying to remote desktop.

Is remote desktop connection enabled on the other PC?

If you have access to the computer, check the IP address, by doing the following - go to in and go Start > Run > Type cmd > Hit enter > Type ipconfig > it will list all the network IP addresses, try that.
