Give an explanation of what happened with this user in each case of the following and as an administrator find a way to support him:

Case 1: A user logs on to his machine locally. He proceeds to work on his projects. After a few hours of work he attempts to save the work to a network location, but whenever he tries to access it, he gets a prompt to enter a username and a password. He tried a few combinations and they did not work, preventing him from saving the work on a network share.

Case 2: You are administering a network connected to the Internet. Your users complain that everything is

slow. Preliminary research of the problem indicates that it takes a considerable amount of time to resolve

names of resources on the Internet.
