You have been commissioned to create a manual covering the installation planning issues relating to the following network servers:

A domain controller
A DNS server
A Terminal Access Gateway
A Web server
A database server
A file and print server
In covering the installation planning issues, you should provide hardware advice in terms of a) system capabilities (internal and input/output); b) which systems should be replicated to ensure high availability [assume 99.999% uptime]; and c) which systems can be co-located on one or more virtualized servers.
