We have server 2008 and we had a bunch of windows xp computers that were in our workroom. They were connected to the domain, and each person has their own username and password. I am installing new PC's with windows 7, and everything works great except for one thing: No internet access.
The XP machines can connect to the internet.
Here is the kicker: you can pull up a single website, but any login / text fields are un-clickable, and you cannot browse to any other site. I killed the antivirus, but that wasn't it. I haven't changed any settings on the domain at all. If you log in as an administrator, you can browse with no problems.
