Can't connect to PC...but PS3 can??

I've been trying for months to get Windows Vista Home Premium to properly communicate with my Xbox 360, but all my efforts seem to be futile. I don't know what it is exactly, but I know that my computer says that it can't reach my 360 for one reason or another.

Then the other day, I buy a PS3 and with low expectations I attempt to view shared files on my computer. I search wirelessly for my network and it finds my computer and all of my music, pictures, and each one of my hundreds of videos. Does anyone else have the inability to connect their 360 to their Windows operating system? It's not really a big deal now that I have a PS3, but I would still like to stream music and such.

PS3 isnt a game console. Its a disgrace to the name

I do get that little icon in my taskbar, it brings up media center and has me go through a connection set-up process, which ends with it telling me that something went wrong. In windows media player, my 360 and my PS3 are both set to "allow." In that same window, however, it does tell me that "sharing is disabled because a network connection was not found." I don't know exactly what that means, especially since the network is working fine, all devices have proper internet connectivity, and my PS3 can access my PC hard drives.Travis281

do you type in the 8 digit code from the 360 during the setup on your pc?
