Folks,
I think I might be having a problem similar to others posted on this forum but I
haven't found the solution here (yet).
I have a PC running Windblows XP SP2. The IP address of this PC, assigned by my
local, wireless router, is 192.168.1.101. There is another PC on my home network,
running Windblows 2000, at 192.168.1.102. Here's the deal:
192...101 (the XP box) can ping 192...102 (2000). The XP box can also access the
2000 box's shared folders and files.
...102 CANNOT ping ...101, nor can it access ...101 in any other way.
The router itself (192.168.1.1) has a ping utility and can ping ...102.
The router itself CANNOT ping ...101 (this tells me that it's not a routing problem).
Both boxes can access the Internet to browse the web, send/receive e-mail, etc. just
fine.
Finally, 192.168.1.101 CAN ping itself, either with that IP address, or with the
localhost loopback, 127.0.0.1.
I have noticed that the XP box receives ping packets but does not transmit responses.
I determined this by watching the network connection status while pinging the XP
box from the 2000. The received packet count increments by one for each ping but
the sent packet count does not increment.
I HAVE ALREADY TRIED COMPLETELY DISABLING THE FIREWALL and I have no other, third
party firewalls installed. I did find some other IP and ICMP security crap while
poking around in places that I probably shouldn't have been in Windows administration
land but that didn't seem to make any difference either. By all appearences, it
looks as though, at the very least, ICMP should be 100% permitted.
Any clues? All serious responses appreciated.
Cheers,
G
