During your lunch hour, your old college friend Dmitri, who works as a net-work technician for a global news service with 200 networked locations along the Eastern seaboard, calls you for help. Usually, five other technicians are on duty to help him handle technical problems. Today, however, two of his cowor-kers are out sick, one is away on jury duty, and another has not shown up yet. That leaves Dmitri and one other technician to solve all of the problems that have occurred on this particular morning, including the following: . A WAN link is down between the Washington and New York locations, causing traffic to be rerouted from Washington to Boston, then to New York. As a result, customers are complaining about slow performance. . The Albany, New York, location's network appears to have suffered a catastrophic failure. This failure has caused outages for thousands of customers in the upstate New York region. . Three executive users at Dmitri's corporate headquarters in Boston cannot retrieve their e- mail, and they are calling every five minutes to ask when the problem will be fixed. A networked printer that provides services to the Accounting group at the Boston headquarters is not accepting any print jobs. The users have asked Dmitri to troubleshoot the printer. They need to send out invoices to customers by noon. . Half of the workstations in the Marketing Department seem to be infected with a virus, and Dmitri is worried that these users will copy the virus to the network, thus risking widespread data damage. Dmitri asks for advice about the order in which he and his other colleague should address the problems ( or which ones to address simultaneously). What do you tell him, and why would you place them in that order?
