I'm trying to help someone I work with. They arerunning Windows XP SP2. About a week ago they tried to install CA's EZ Trust. It didn't install correctly so they uninstalled it. After that, IE could not get to and display any web sites. It fails with the error server not found. I have run IE Fix and Winsock XP Fix. I can ping and tracert using hostname or IP. I can do nslookup without problems. Today I downloaded Firefox to my machine, put it on my zip drive and loaded and installed it on their machine. Firefox has the same basic problem but returns a timeout error. I installed Sharkwire (previously known as Ethereal). I see an http packet coming back from the web site but the destination IP is not the same as the machine I'm working on so I presume there is a proxy somewhere.
Any thoughts are greatly appreciated !!
