A fellow student asked for your help in diagnosing a problem with a Windows computer. He believes there is a problem with the network adapter. He works in a small office and does not know the credentials for the Administrator account on that computer. The person who does know is out of town and is unwilling to give him the password until he can convince her that there truly is a problem. He wants to use Device Manager to see the status of the network adapter. What advice can you give him?
