Can't see networked PCs

[Guest]

I have a vista PC and a XP PC networked via a Linksys wireless router,
sharing a broadband internet connection. For 3 weeks I was able to see the
XP from the Vista and share/use files, but not the other way. Internet
connection on the XP (the wireless pc) was excellent. Now I can't see in
either direction, but Internet connections are still excellent on both
computers. What is going on here? I'm pulling out my hair! I'm relatively
savy, but certainly no whiz...who can help?

If turn off the firewall, can you ping each other?

Even with the firewall on, ping is successful both directions
