Can't see other network computers...

[crowland2]

I have a home network using a netgear router. I"m working on a friend's computer and am trying to add it to my network but can't seem to get it going. It's Win98 and 3 of my 4 computers are winxp, but my other computer in the network is Win98 and it's running fine. On my friend's computer, I have internet access throught my router. I can ping the other computers, but I can't open them up with the network neighborhood. I get an error telling me to do the network troubleshooter. When I try that, I only get to answer one question, and nothing else comes up. My other computers are shared and I can access the files. From my computers, I can see the name of my friend's computer, but can't open it up (the files are shared). Does anyone have any obvious ideas? Thanks!

Oops--forgot to mention she had the same problem on her network. She had internet access but couldn't see the other computers.
