I'm of thought it is firewall on your "problem" box is issue. Doing a ping to
host on same subnet should result in fairly straightforward icmp/unicast
message sent directly to node. Not much to get into way except firewall.
Have you tried messages other than ping/icmp? Try doing a telnet or ftp or
ssh or "telnet 80"...can you see other nodes in network neighborhood?
What does "arp -a" show?
1. Try tracert using ip of router. Should result in single hop to dest.
2. Boot windows in "safe"? mode and attempt same there. Safe mode doesn't
start a lot of extra svs.
3. Install ethereal on problem box and capture network traffic while you're
doing ping. Be sure not to capture in promiscuous mode (if you have a hub
instead of switch) as you'll get too much traffic.
This tool provides smart formatting of network traffic...check for ICMP
traffic...a ping req and corresponding ping reply.

but cannot ping the router (192.168.0.1) or any other IP address.
Turned off firewall on the desktop, went to services and task manager and
made sure that no other firewalls or unusual processes were running.
Completely scanned the PC with Mcafee to be sure there were no viruses.
ipconfig /release & /renew work fine, but still no ping.
Thanks in advance for any ideas!
