Computers 1, 2, and 3 can see 4, 4 can't see 1, 2, and 3. Internet connection OK.

I have 4 computers connected to my network.  The first three work fine including printer sharing and internet connection sharing.  I am trying to add a 4th.  It is running XP Pro (as are the other 3).  I can see computer 4 in My Network Places on the other 3 computers.  I CANNOT see the other 3 computers from computer 4 in My Network Places.  Internet connection works fine.  I'm sure this is just something set wrong.  I have NVIDIA firewall running (it came with the ASUS motherboard in the 4th computer).  None of the computers were seeing computer 4 until I created a custom profile for the firewall that specifically allowed the other 3 computers by IP address.  Any ideas?  Thanks!

Hi blondy,

check that you have netbios enabled

also turn off windows firewall/ICS and application layer gateway

can you ping the other machines and can the other machines ping the new one

just a couple of starters :)

Cheers!

blondy,

also disable the NVIDIA firewall for a little bit and see if that causes the problem

Disabling Windows Firewall did it.  Everyone can ping everyone now.  :) I knew it must be something simply set incorrectly.  I should have thought of that.    Thanks a lot!
