John is a PC technician for an organization that has a computer network with 12 computers. Each contains vital information, so each uses static IP addresses. John just finished troubleshooting a Windows 8.1 computer that could not access the network. He ascertained (correctly) that the computer needed a new network card. He purchased a Plug and Play card and physically installed the card. He then turned on the computer, noting that the network card’s LED link was lit and that there was activity. He then rebooted the computer to Windows and then documented the whole process. Later, his boss tells him that the user is complaining that she cannot access the Internet. Which step of the A+ troubleshooting theory did John forget to perform?
