I was taught this trick by a great ninja master and thought I would share.  Say you need to get access to a server, but RDP isn't enabled.  You have full admin rights but for some reason or another you just can't get physical access to the machine so you absolutely need remote access enabled.  Well, just drop this command in and shazam! RDP is enabled.
