Hi Guys, I thing this will be an easy one for all of you. I work in a small office with 9 computers that are conected through a small network. I'm thinking of buying small business server 2003 standart so we will have a proper network. I have few question since I have no idea: 1. Does all work stations need to be XP Pro? (I have some home and some Pro). 2. How difficalt it will be for me to build and configer the server mostly exchange and share point. My main use for the network is share internet/printer and files. I want to use the sharepoint as an Intranet. Is it the right use for it? (I will buy the server pre configur but after that - mails,users, firewall etc.) I have now background as network admin but I have a good sence and good will so let me know if I can do that.... Thanks, Assaf
