Windows 7: Windows will not connect to school's Internet, Ubuntu will

Hello all,



I've had my computer for a little over a year. Since I've had it, I've not been able to connect to my school's WPA2 enterprise WiFi connection OR using an Ethernet cable using windows. However, it does work on every single other WiFi connection I've used. I have Ubuntu dual booted and it connects with the school's Internet just fine. I've used Ubuntu for school Internet since I've had my computer but now I have to have Windows + working Internet for a class I'm taking.

When I use an ethernet cable and WiFi it says the DNS server is not responding.
This is what I'm basically looking at:

I took it to the IT people here at my school a while back and they messed with it for about 2 hours, downloaded some drivers, did an IP renew, and still no dice. They basically had no answer for me. I really need to get this figured out because it is really damn annoying and if I have to buy an entirely new computer I will be furious, and I don't have any money for that at all.

Any help is appreciated. If I need to post screenshots of anything I will.
