We currently use a work group environment in our office and have a total of about 50 PCS which can increase in the future. We are in the process of setting up a server environment and needed help on the same. We require 2 servers, one would be our domain controller,dhcp server and the active directory. The other will be a file server and an exchange server for our email applications. Can someone help me out with a step by step procedure that would require to be carried out in setting up of the servers? Server OS will be Windows 2003 Server. The servers will also require to support Raid 5, so can you also advice recommended motherboards with on board raid controllers and a decent processor for the same. I have to achieve this in short span of time so please advice in return at the earliest.
