But call your Work IT support. The only hope I see in self support is to do this -> http://support.microsoft.com/kb/299357
As it stands you could turn off the firewall.
Hoping someone can help me out. I recently started a new job and was given a Dell Latitude running XP Pro (model # worn off or I would provide). When I brought it home and tried to connect to my Comcast broadband connection through both wireless and ethernet connections, the connection isn't recognized. I can plug the cable into my desktop and another laptop and it works for both. The work laptop recognizes the wireless connection but shows as "limited or no connectivity", whereas my other laptop connects just fine. My gut tells me it is a firewall issue. Someone suggested unplugging the power and battery, then reconnecting with the ethernet plugged in... no luck. I'm really hoping to work from home and not have to drive in to work as often (gas $$$ are raping me!), but I need to get online to do so. PLEASE HELP if you can!!
Thanks so much,
