Trouble logging into TechRepublic

I’m having a problem logging into TechRepublic with my laptop. It’s running XP Pro, all updates applied.

When I try to login, the browser searchs for awhile & then I get a DNS error. I can login when I’m at the office with my laptop, and I can login with another machine from home (NT4 server/Win 2k pro).

I’m using DSL behind a Linksys adsl/cable router. The settings from ipconfig look the same on all machines with the exception of the adapter description, MAC address, and IP address.

Any suggestions?
