I have 4 win98se computers  on a home network.

The network:
Cable modem/linksys router/3com hub

Two of the computers are conected directly to the router(I'll call them #1 &
#2), the other 2 are conteced to the hub(I'll call them #3 & #4). #1 is able
to see #s 2, 3 & 4 but not it's self. #'s 2, 3 & 4 are all able to see #'s 2,
3 & 4, as well as use each others printers, cd drives, etc. I've checked and
all settings, on all 4 machines,  (I believe) are set up the same.

Help please!
