Windows 2000 ADV Server

Hello, My question is this. For collage I have a project which is to design and plan out a network for a company which we create. We can work with only Windows 2000 Advanced Server and Windows 2000 Pro and we have 10 computers to make this work. What we decited to do was plan a gaming company we would have 4 Servers, Install DNS, DHCP, RIS, NAT and Active Directory. We have to ensure this is a 3 hour thing and set it up infront of the instructor however according to the 5 techs we have that will not take 3 hours but less. Is there anyother Windows 2000 Advanced Server features we could throw in to extend our plan for 3 hours?
