Error message

We had Norton Internet Security installed on on desktop PC but the hardrive crashed and we had a new hardrive installed.  I am trying to download Norton to the new one but keep getting an error message.  The message is:  this process is unable to continue due to a system service that may not be installed or cannot be started.  Please repair your installation of windows before continuing.  I follow the instructions on the following page and can locate the services.msc box but it asks me to update the Terminal Services to Automatic.  I cannot locate this under the services box.  Step 2 tells me to update the Remote Procedure Call to Automatic which I have completed.  Can anyone help me with the Terminal Services?  Is this possibly listed under something else?  Please let me know what I can do next.  Thanks.
