Just bought a new computer and put XP corporate on it. The other day I tried to map to a folder I had on it and it wouldn't map and I know that it is shared because it's setup like my old computer is. Then I tried to ping the ip of that pc and it would time out. So I tried to ping the pc from itself and it won't ping there either. I can ping the loopback address and the default gateway though. I tried to reload the mobo drivers and that didn't work and tried resetting the nic with the netsh int ip reset netlog.txt command. Looks like XP doesn't allow me to un & reinstall tcp/ip. Just wondering what other option there might be. The computer can surf the internet just fine and does pull an ip. I have the internet connected off a router and it goes in via USB to the pc. Also noticed that if I plug into the cat5 nic that doesn't work either. Any ideas are appreciated. Thanks.
