A large law firm, Block & Diddle, employs over 800 lawyers. Most of the lawyers work in the firms main office located in the city, and some lawyers work in the firms smaller satellite offices located in surrounding areas. The law firm hired a network manager and a network technician to setup and maintain their computer networks in all offices. However, after working for the firm for a couple of years, both the network manager and network technician left to pursue other jobs. Rather than hiring people in their place, the firm asked a few of their lawyers with some I.T. background to take care everyones computer needs on the side, thinking this would be sufficient since the networks were already setup.

Some time has passed, and they are now experiencing some significant network issues that they do not know how to solve. Block & Diddle has hired you as a consultant to identify the problems and propose solutions for their network issues.
