Jordan says she cant access files on the server any more. No other user has reported this problem and she can PING the server from another computer successfully. Typing ping 127.0.0.1 from Jordans computer is also successful. Using PING to try to reach the server or any other computer from Jordans computer fails. A check of IP settings on Jordans computer shows that her static IP address and other information is good. What is the most likely cause of the problem?
