How do I get my Xbox 360 to connect to my computer correctly?

It's kind of complicated. It used to not be an issue, my computer and 360 could share music without a problem, but now the 360 can only find this computer using windows media center on the 360, but can't play the music when not in that mode, anybody have any help? I tried disabling my firewall and I have not changed firewall carriers, nothing really changed, it just stopped working.How do I get my Xbox 360 to connect to my computer correctly?Contact them by phone.How do I get my Xbox 360 to connect to my computer correctly?Does the computer know what the xbox 360 is?
