Lost internet after joining another domain

Specs: Windows XP SP3

Hope someone can help me on this issue -- my laptop could not anymore connect to the internet after joining another domain.

Previously, my office laptop was connect to Domain.A. My internet connection at work is through a proxy server. If I bring my laptop home, I just set it to 'no proxy' if I want internet through my personal wi-fi.

Just recently, my laptop was required to join Domain.B. Unfortunately, Domain.B's Group Policy is notoriously known for its very strict security policies. When I got home that day, I could not anymore connect to the internet, despite the usual no-proxy setting. The page errors are "Server not found" and "... cannot display webpage" for Firefox and IE, respectively. Even if I login to my old Domain.A, I still could not connect to the internet.

I'm pretty sure it has something to do with the domain's group policy and 'disallowed' or changed some settings so that I could not anymore use the laptop for personal internet use.

Can someone tell me what settings I could possibly change through RegEdit or GPEdit.msc?
I'd really appreciate the help!

My guess is you're afraid to ask this question at work & for good reason. If they don't want you to use your work computer outside of the work network, why are you trying to circumvent the security? Sounds like a good way to get fired.

Hi Mickliq,

Actually, I did ask our security and admin folks through a formal email regarding this. Unfortunately after a week and several follow-ups there has been no response yet. Aside from the obvious personal reason, i need to access my work mail over-the-web and/or connect to servers through VPNs, etc., as my work dictates. I'm a project manager, so I really need to be mobile.

Hope this clarifies my overall intention. Thanks! =)
