The most likely problem is that a firewall on each computer is
blocking access from the other.

If the computers run the original or SP1 versions of Windows XP,
disable XP's built-in Internet Connection Firewall on local area
network connections -- it's for use only on a direct modem connection
to the Internet. If they run SP2, turn the firewall on and allow
exceptions.

Disable and un-install all other firewall programs (Norton Internet
Security, ZoneAlarm, etc) while troubleshooting. When un-installing a
firewall program, use the un-install procedure provided by the
manufacturer . Don't use Control Panel | Add or Remove Programs,
which might not completely un-install it.
