Do those 2 computers connect to hub or switch ports that support 100
mbps speed?

Try switching cables around. An improperly wired cable can work OK at
10 mbps but not work at all at 100 mbps.

The cards might have their network cards configured for 10 mbps speed.
If there's a 3COM utility program that came with them, run the program
and configure the cards for 100 mbps. If there isn't a program, set
the speed as shown here:

Thanks so much, Steve! Come to think of it those 2 computers probably are
on a hub, rather than the router. I'll check all of your suggestions out &
let you know what I find.

Again, thanks! I really appreciate your help.

Solution Found!

Thanks, Steve, for your kind and generous help.

This problem (like the Add Printer problem that I was experiencing on RMS3)
was caused by either a defective router or an improperly installed router.
It was completely resolved by exchanging the router and carefully following
the installation instructions for the replacement. I
exchanged the original LinkSys EtherFast 120/100 4-port Cable/DSL router
model BEFSR41 for exactly the same router at LinkSys Tech. Support's
encouragement. It's entirely possible that I made mistakes installing the
first router.

Anyway, this was not a Microsoft problem. And, I'm happy to report that the
new router works extremely well.
