We are having issues with a single computer on the network...

Domain - Server 2003
Desktops - Windows XP SP2

This ONE computer is able to ping all nodes on the network, but no
nodes can ping it. Tried pinging by IP and Hostname... both come back
unpingable...

YET, that computer is able to reach all servers and network resources.

We have tried getting a renewing the IP address, rebooting, checked
TCP/IP settings on the device, and everythings set to Dynamic and
nothing out of the ordinary.

Does anyone have any ideas on what we can try?

BTW. Windows built in Firewall has been disabled.

Thanks in advance.

This is most likely a misconfigured or overlooked personal firewall, or other
security component.  What antivirus products do you use?  There are several
other possibilities too, and any might be the cause of your problem. Read this
article with an open mind.

You could look at "browstat status" and "ipconfig /all", from the problem
computer, and from 2 others, and diagnose the problem.  Read this article, and
linked articles, and follow instructions precisely (download browstat!):
