We have a network at our school and in one of the labs we added t 8-port switches so we would have so many cable laying on the floor. Everything worked just fine for the first few days with no noticeable decrease in performance. Suddenly, yesterday afternoon, all of the client computers started stalling when the students tried to log in. It would go to the screen that said "Loading your personal settings" and would stay there for as long as 5 to 10 minutes. Any suggestions on how to alleviate this problem?
