Are the other machines XP?

If not, I expect you've got the built-in XP firewall operative. That
will not respond to unexpected pings.

Help, firewall, yields:

To enable or disable Internet Connection Firewall
Open Network Connections
Click the Dial-up, LAN or High-Speed Internet connection that you want
to protect, and then, under Network Tasks, click Change settings of this
connection.
On the Advanced tab, under Internet Connection Firewall, select one of
the following:
To enable Internet Connection Firewall (ICF), select the Protect my
computer and network by limiting or preventing access to this computer
from the Internet check box.
To disable Internet Connection Firewall, clear the Protect my computer
and network by limiting or preventing access to this computer from the
Internet check box.
  Notes

To open Network Connections, click Start, click Control Panel, and then
double-click Network Connections.
You must be logged on as a computer administrator to complete this
procedure.
If you clear the Protect my computer and network by limiting or
preventing access to this computer from the Internet check box, the
firewall on your computer is disabled, and your network is vulnerable to
intrusions.
You should not enable Internet Connection Firewall on virtual private
networking (VPN) connections or on client computers because ICF will
interfere with file and printer sharing.
ICF cannot be enabled on the private connections of the Internet
Connection Sharing host computer.
Internet Connection Sharing, Internet Connection Firewall, Discovery and
Control, and Network Bridge are not available on Windows XP 64-Bit
Edition.
