I'm not sure if it was because of installing hamachi at one point, but for some reason, it seems that my file sharing is finicky. I was trying to get my Windows Media Player 11 to share my music to my new 360. Essentially, it should work. My 360 doesn't see it. Well this is the part that makes sense it has to be my computer... randomly, my system will decide not to be seen on the "My Network places" which can cause issues for my roommate and I to get stuff done. Heck, even at times, the LAN, I completly disappear from the network, but can still access the internet so I'm not completly off the radar. Any help or advice would be appreciated to solve this issue.
