I have a home LAN with router, cable modem and 3 computers. One is a (new) laptop connected wirelessly. In windows explorer, each computer can see the others, but Computer 1 (DesktopA win xp pro) can ping computer 2(Laptop win xp pro ) and Computer 3(OLD PC win 2k), but computer 2 and computer can not ping the Desktop, and 2 and 3 can ping each other.
All have similar ipconfig:

I have removed windows firewall, virus checking, etc. but nothing has changed.
Is there some setting in Desktop that would prevent being ping-ed? Is there some software (TCPIP) that might be corrupted and need to be reinstalled?
