Internet Gateway in Network Connections, No internet

Running Windows XP Pro sp3

I am trying to connect wirelessly at home with my work computer (it is a domain computer at work, if that matters).  I have no problems with wireless on any of my personal computers, but when I bring up the work computer this new connection shows up in Network Connections under the heading Internet Gateway.  I found on some forum to uninstall it by ControlPanel->Add/Remove Programs->Add/Remove Windows Components->Networking Services->Details>uncheck the Internet Gateway.  I did this, but I still dont have internet at home with work computer.

I did this and it is gone from Network Connections, but still no internet.  I CAN, however, connect to my office via VPN.  Just no internet.  ipconfig gives a good IP configuration.  I have tried releasing, renewing, flushing DNS.

One thing I noticed when the Internet Gateway was there is that I could get to google.com by entering in its IP address, but not its FQDN.  With the Internet Gateway connection gone, I cant even do this now.

I do not have this Internet Gateway connection on any of my personal computers at home and I have no trouble connecting to the internet.  I can access the internet at work with the work computer, via wireless, without a hitch.

This is all a recent occurrence, and is happening with 2 computers.  Mine and another employee who works from home.  It may happen with others, I just havent heard anything yet. Please help

Simply being on a domain does not prevent a computer from using Internet elsewhere. Did your company install a proxy on your work computer? Check the proxy settings to see if something is checked there that should be unchecked at home. Be aware that proxies can be created by installed programs and then you will need your company support. ... Thinkpads_User

The DNS settings on the work computer probably have a local DNS server setting and when you are outside of the work network you won't have DNS resolution.  You can add a second DNS server to your settings.  A public DNS server like 4.2.2.2 or 4.2.2.1 should work well for you.  There are many other public DNS servers to choose from (google search it) but these two are the easiest addresses for me to remember.

Also, when you are connected by VPN, most VPN's will default to disallow internet browsing (called a split connection) while connected to the VPN.  You may be able to change this on your client but you may or may not be allowed to depending on the VPN concentrator settings at your work.

Nope, no proxy.  No, being on a domain shouldn't matter, but that is the only substantial difference between the work computer and home computers.  I have used other work computers at home before, but this is a new occurrence, and it is on more than one computer.  One of the computers is brand new from Dell and the other is a 4 year old Sony. Both with sp3

UPDATE
I dis-joined one of the computers from the Domain and I can now get internet connection at home.
I need to have the computer on the domain though.  What in the heck is causing this and what is the work-around.  I suspect it has something to do with sp3, but I can't uninstall it from the new computer b/c it came with sp3.

No, it isn't DNS, b/c I tried that.  Also, I am disconnected from the VPN when I try the internet b/c our VPN does nix internet connection when connected to it.

I still need help.
I have uninstalled Service Pack 3 on yet a third computer and still can't get on the internet, via wireless, outside of the office domain.  The only way that I have found is to disjoin it from the domain, but this is no solution.  Any ideas are greatly appreciated.

In your picture above, you have "Internet Connection" What is "Internet Connection" /\?
In the same picture, wireless is active and wired is not. Can you temporarily disable Internet Connection, turn off wireless, plug in a network cable and see if the same thing happens.

I am attaching a new picture that will show the thing better.  Notice the title "Internet Gateway"  What is this thing?  As soon as I connect to a home router, whether wireless or wired, it pops up.  When I get back to the office it is gone.  Again, this is happening on all of our laptops.  I tried what you said above, but still does not work.  I took the new Dell and restored it back to factory and joined to the Domain.  Did NO Group Policy updates, Windows updates, or anything.  Still the same problem.

You should determine how "Internet Connection" got installed or added to your network connections under Internet Gateway. I do not have that running anywhere (my own machines, XP machines I just checked that are on a domain). If it were my box, I think I would be inclined to disable or delete it. I would check first to see if I could determine how it got there.

Since you have added new information:
1. You re-imaged the machine and have not added anything, and
2. All your laptops are affected the same way,  

then:  Consider re-imaging one more time and do not add it to the domain. Check that all is well with respect to connectivity. Do not add or subtract any software from the re-image. Finally add it to the domain and see what happens. If just adding it to your domain causes a problem, there is some policy or script on the server that is adding software.

Does your server add proxy software to the machine? If so, therein most likely lies your problem. ... Thinkpads_User

Thanks thinkpads user.
Yes, I have done all of that.  The problem DOES occur as soon as I join it to the domain.  However, we did not add anything to our Group Policy prior to the problem starting.  Also, I have a Windows 7 RC laptop that I have fully updated with Window Updates and Group Policy.  This machine has no problems getting online at home.  It is only XP.  We run a Server 2008 x64 DC.  
Oh, and no, we have no proxy software, or not by choice anyway.

I have joined lots of XP machines to a domain and they do not have a problem connecting to the Internet when not on the domain (but still domain machines). Further, a number of these machines are running SP3. So I do not know what to suggest next.

(a) Almost all servers will run a script by default, so check the script iself (not the group policy).
(b) All my client servers so far are Server 2003 32-bit. Check this. There may be something in a Server 2008 domain that is affecting you, although I do not know what.

I figured it out, finally.  It was a DNS setting in Group Policy that I didn't know someone else had set up.
It set the DNS servers as our DNS servers, however, when you leave the office, the policy will not let you use any other DNS servers that are not specified in the policy.  Sooooo, we added a public DNS server to the policy, and wallah.

Thanks for all your help thinkpads user

That is pretty much as I figured
                 "The DNS settings on the work computer probably have a local DNS server setting and when you are outside of the work network you won't have DNS resolution"

Glad you were able to find where the DNS was getting applied from.

This is my first question to ever post.
I would like to accept my own answer as the solution, but award some points to another.  when I click on accept multiple solutions, mine does not show up.  How do I do this?
