Windows 7 Internet Access Trouble

Ok, I have built our first Windows 7 Test Machine. The only problem I am having is that it says I have no internet access, although I actually do. We have an ISA Firewall Client that the machine autenticates with. It gets out to the web just fine and the network is working just fine as well. The only thing is that on my connection icon it has the yellow sign and says no internet access. Any help would be appreciated.
