Home Network over Router connection problems

[garfield1979]

Hey everyone, I've hit a brick wall:
I've purchased a network router to share my Cable connection to both of my PC's. I've put both the PC's on the same work group, and i've been able to see the Computer names when i go to network neighborhood, or when i try pinging the respective computer name.
PC1 (old pc)
PC2 (new pc)
When i ping PC1 from PC2, it doesn't work, the pings time out, but it resolves what IP PC1 is using.
When i ping PC2 from PC1, it works, the pings go through.
Needless to say i can't share any files from PC1 on PC2 and vice versa even if i've setup their shares.
The internet sharing part works without a hitch. which is what the whole operation was for in the 1st place.

What strikes me as odd is that the names resolve the IP address, but yet i can't get a ping from the IP, but i do get a ping when trying in the other direction (PC1 to PC2)

I am not by any means a novice at this kinda stuff, i've dealt with wireless networks and more, without problems, but this is just boggling me.

please provide any help you can, i'd appreciate it greatly.

Thank you in advance.

Chris

Configuration:

PC1=Windows 2000
PC2=Windows XP
Router: Linksys Network Everywhere 4-Port Cable/DSL Router

I should also say that the two computer are obtaining good IP addresses from the DHCP in the router.
I have the option to boot PC2 on windows 2000, i havent tried that yet, but it may work, but only as a troubleshooting capability, as i want to use winXP.

Anyone with any input will be greatly appreciated

Is there any firewall software running on the machine that can't be pinged? (PC1 if I'm reading right).

But i still tried sharing files on PC2 and i wasnt able to access them from PC1, but then again i just tried once.
