Setting Up a Linux Server
I suggest you use SuSE (from Novell), or Centos ( a flavor of RedHat) if you are a new comer to the Linux environment. The reason for the choice of either OpenSuse or Centos is the support for these product and the relative ease with which you can set them up. Both distributions have nice GUI front ends which makes the Microsoft technicians feel at home.

Install Linux as a powerful and robust server
Usually during the initial installation you get to choose the packages you would like to install, and the roll that you server will fulfill. So for those not familiar with the Linux terminology here are a few things to be aware of.
Desktop environments (the graphical user interface, or GUI)
there are a few to choose from, but either Gnome or KDE will probably be the best choice for a new comer. In fact KDE will remind you somewhat of a Microsoft PC.
Web Server
For a web server you will want to install Apache (or Apache2)
Proxy Server
Linux ships with something call Squid which can turn your computer into a powerful Proxy server. A proxy server allows you to control you employees access to the Internet. For reporting on users Internet usage you need to install SARG, which you might have to down load off the Internet since SuSE at least doesn’t ship with it.
File Server
If you will be using Microsoft workstations then you will need to install Samba. Samba uses the same protocols that Microsoft uses to share folders on the network. Samba can also be configured to make your Linux server act like a Microsoft Domain controller.
Mail server
I suggest you install Postfix as the SMTP part of a mail server and either Qpopper or Dovecot for the POP or IMAP side of the mail server functionality. You need a mail server to be able to handle both sending (SMTP) and receiving requests from the mail clients (IMAP, and or POP). Qpopper can handle POP but not IMAP whereas Dovecot can handle both. Qpopper is a lot easier to setup.
