Hi everyone, this is my first post here, and I please hope that you guys can help me out here. The problem started yesterday, literally right after I downloaded internet explorer 8 to my computer (if you are wondering, I use vista). After the download and restart, everything seemed to be ok with my computer, until I wanted to stream some music from windows media player through my Xbox 360 while I was playing. I then get a message that says it cant connect to my computer, and to check my media sharing settings. I try to enable it again, and it says there might be a firewall problem. I disable my firewalls, try it again, and it still wont go through. I did anything and everything I could think of, even one of my good friends (whos the IT department director at his job) tried everything he could and it didnt work. My Xbox 360 and Playstation 3 cant even connect to my computer through my network anymore, its as if my computer is invisible to everything. He said to copy the WMP settings from another Vista enabled computer, which I will do, but it is probably my last and best shot. I tried to run system restore, but my computer has no real usable restore points, so that didnt work. What should I do?
