Trying to add a XP-Pro computer to a network just to share the internet connection. Currently, there are about 12 computers running off a hodge-podge of hubs, routers??? It can see/access shared folders in all the other PCs but cannot get on the internet. The same is true for pinging - it can't find the servers for web addresses. Don't know all the specifics about how it was was set up since it was done a long time ago (5 years) and no one there knows anything about it. I've pretty much ruled out software problems, which I'm most familiar with, and am pretty sure it's a hardware issue, which I'm not so familiar with. I brought it back to my office (which has the same type of network) and it immediately connected. However, in their office, even when I've tried moving it to different hubs, switching cables, etc., it gives me the same problem everywhere. What am I missing? What should I be looking for?
