[SOLVED] Internet Access only for Administrator problem?

[Teletubby]

Hey, for some reason today, one of my computers has lost internet access for all accounts except my main account which is an administrator account (as opposed to a limited account). The computer is running Vista Home Basic, and my network topology is like this:

Computer <-Wireless Connection-> Dlink WBR WAP/Router <-2Wire Gateway from ISP-> The Internet


Vista doesn't notice any network issues, and I can ping both the router and gateway successfully. However, I just can't get any access with the 2 limited accounts on the computer...my main administrator account has no problem accessing the internet though. I flushed DNS, and renewed IP addresses already. If it makes any difference, I am running OpenDNS on my gateway, but all the other computers in my house have no problem accessing the internet. What makes this even harder to figure out is, the suspect PC was working fine this morning, and just lost internet access all of a sudden...all without loss of connection to the main network.

Weird fix...very very weird.

I still continued to experience this problem throughout the day today, no internet access at all. So, I went into "internet options" of internet explorer, and then went to the connections tab. There were no connections listed (which is fine), but I decided to click the button to Add a connection anyway. A prompt then popped up, and told me I was already connected to the internet, and then gave me a couple buttons to push, one of which said something like "Browse the Internet". Clicked that, it opened firefox, and I had internet access again. Weird, but true. And right before I tried this fix, I checked internet access, and had none, so it had to be this "fix" that solved the problem! Weird.
