I bet the new network needed a new server and then you have to set that system up to work with all the client computers in the building some software sided stuff, intranet ect. Maybe some new client computers. Loads of planning how to wire up the building, hopefully something like that is just replacing the old cabling so its easier that way, maybe some routers and switches. Setting up the routers and switches and managing the ip addresses (static ip addresses).
At college i wish i did HND Networking, I did almost a year of Tech Support and then left college.
