I had a problem with tunes remote for the longest time... What I did to fix my problem, was all of the itunes sharing stuff.... and then go to your security center on your computer. Click on windows firewall and make sure you have "DON'T ALLOW EXCEPTIONS" unchecked. I did that and it's worked perfectly ever since. I did have to input my ip address manually. A playlist pops up in itunes named "REMOTE" click on that and enter the 4 digit code. You should be in business after that.
