This seems like a problem that would have an easy fix, but after multiple google searches and searches through solutions on this page, I've been unable to find a reason I'm still getting the problem. I'm running Win XP Pro and have no problem connecting to the Internet or any local network I'm plugged into. The problem is that I cannot ping any addresses (save the loopback address) without getting "destination host unreachable" as the responses. I've checked the routing table and it seems like it is correct, but I still get the same response. For instance, my computer is currently configured with IP address 192.168.104.201 on my company's internal network, which is 192.168.104.x mask 255.255.255.0, and I'm trying to ping any other computer on this internal network. In the routing table, there is a route of 192.168.104.0 mask 255.255.255.0 gateway 192.168.104.201 interface 192.168.104.201 metric 1. The default gateway is .253. Is this route wrong? This is really annoying as I'm trying to test the connectivity of another device on the network but can't use ping.
