I am working for an automotive group and am in charge of setting up some new computers for the sales department. They were running windows xp on some of their computers with the internet working just fine through an ethernet connection. I went to install the new computers that have windows 7 professional on them and the computers recognize that an ethernet cable is plugged in but no internet access is available. This has happened multiple times to me. I've gone through all the settings and properties that I could think of. What could be going wrong?
