Hi, After searching these forums and coming to my wit's end (albeit, not a long journey), I have run out of ideas. Here's the situation... I have a dual boot Sony Vaio PC - Suse Linux and Win XP (OEM version, not SP2 unless SP2 ships with OEM systems now). The computer is new. My internet connection goes through a SMC Barricade Router to a cable modem. When I use Linux, I get an internet connection just fine. It establishes the IP, domain name, etc right at start up. However, with XP, I cannot get a valid IP address (i.e. a non-private IP address). I am using the onboard ethernet port (an Intel PRO1000) with TCP/IP set to get the IP and DNS automatically. I have tried to enter in a manual IP and at least connect to the router but have not been able to do that even. Also, if I connect my PowerBook using the same ethernet cable and router port, I can connect just fine as well. When running ipconfig /release ipconfig /renew, it times out and says "unable to contact your dhcp server, request timed out ". I checked to make sure I have my DHCP service started which I do. The funny thing is that the internet connection in XP was working for a brief moment in time. It was running somewhat "choppy" so I thought I'd release/renew the IP address and from that point on, it hasn't worked. We have 2 other desktop's connected to this router that are working fine and 2 notebooks wirelessly connected that are also working fine. I've even tried switching ports on the router and that did nothing as well. I've put together home networks for people so many times and have never had a problem when using an ethernet cable, only in setting up wireless so I'm even more dumbfounded by this. Any help or pointers is greatly appreciated. Thanks.
