dmarkow 0 Posted November 9, 2002 I have a computer with xp pro that is having trouble pinging localhost / 127.0.0.1 Also, it can't ping it's own IP address, 192.168.1.107 However, it CAN ping the router, and any address on the internet. It just can't see any other computer on the internal network. I tried resetting the tcp/ip stack using netsh int ip reset but it didn't help. Also, the network card was working perfectly fine before i upgraded from xp home to xp pro... could the upgrade possibly have screwed something up? Share this post Link to post
