My colleague reformatted the Vista Business computer on our shared workstation and when I tried to go online, “The page can’t be displayed”. I thought it was just a proxy setting but after further troubleshooting I found out that the “network adapter is not installed and configured”. Manual installation by browsing the CD content and backup files won’t do the trick so it leaves me not connected to the Internet.
Save yourselves from the hassle of searching for solutions online. Google is not that reliable at times. Using another computer, head to Dell Support Homepage if you are using a Dell computer (obviously).
