I'm back at school and have my PC and my PowerBook both plugged into a small Linksys hub. Both computers have "Share my music" and "Look for Shared music" enabled. My PowerBook can see the Shared Music from my PC, as well as many other computers on the university network, however, my PC is unable to see any Shared Music at all. And again, yes "Look for shared music" is checked on my PC. I have no firewalls or anti-virus software or anything on the PC. Any ideas? I was able to do this last year with no problem... what's the deal??? Thanks in advance!
