You should be able to do it by IP address, or by machine name. If port =
445 is opened, then you shouldn't have any problem. Since you're behind =
a router, have you tried turning XP's firewall off? If that works, then =
its definitely a firewall issue.

Any other suggestions?

ICMP Echo is the same as a Ping. Port 445 should be the port that =
ping's come in on.

Oops, I see that in your message now...

Ok, on both PC's I've got the option "Allow incoming echo request" =
checked=20
but nothing else. I don't see anything about "Ping".
Is there some port that I need to enable (and how)?

Is the Windows firewall enabled? If so, check the firewall =
