Remote control without the remote or the control

You’ve configured one of your workstations to act as a host for Remote Desktop Connection, but other workstations on the network cannot connect to the host. All of the settings in Remote Desktop appear to be correct. Which of these is the most likely cause of this issue?

A) The Remote Desktop service is not running

B) Your Windows credentials do not have permission to use Remote Desktop

C) Windows is not using the correct network adapter

D) The Windows Firewall is not properly configured

E) Are your remote control batteries working? If you point an IR remote at a digital camera or phone camera, you can see the IR light blinking when you look at the camera viewfinder. #tipoftheday
