Can't see the Files in another computer

[foolygoofy]

Hi all

I have a 4 network computer, one computer runs 98, two run on xp and the other vista. After the network was set up, I'm having problems with one of the XP machines. You can see it in the network, but you can not see the files in that XP machine. Everynow and then the computer will disapear from the network and then come back after a while. I'm sharing the C drive in all of them and in the other computers I can access the files, but it's that machine, the most important one that it is giving me issue.

Could it be a Firewall issue or antivirus blocking me. Two run Norton (Vista & 98), one nothing (XP) and the one giving problems has McAfee.

Any tips?

Thanks

Probably a McAfee issue. Be sure the firewall is set to allow your local LAN or whatever terminology they use.
