You can’t print on the printer down the hall, and you can’t run certain programs. The problem may be that your computer is not communicating properly with the network to which it is normally attached.
Trying to solve most network problems is not for the faint of heart. One thing you can try is to check the cables in the back of your computer. Is the network cable firmly attached to the computer? Try wiggling it a little, even if it looks okay. Otherwise, it’s time to call in the experts.
