So my school signed me up for a competition tomorrow that I have no idea what I am doing because a kid dropped out and they needed someone to fill in. We have to build a network using routers and switches... I have a general idea of what I am doing but could anyone shed some light on this or tell me any tips? I talked to the other people in my group that I was put with and none of them have any idea what they are doing.

This is all they give me: attempting to build and configure a Windows 7 network, using the provided Cisco 2901 routers and Cisco 2960 switches. The architecture and design of the network to be built will be revealed when the competition begins.
