IN a small company with security and cost as factors in your NOS try looking AWAY from MS solutions, the licencing will eat your budget as well as the fact that you have to pretty much purchase every licence separately for the various products.
Enter Novelll Linux. Novell has a phenominal history of building secure NOS's that allows more simultaneous logins and processes than Microsoft does, Linux is known globally for it's security and stability that reduces Netadmin work a thousandfold when compared to MS and the need for multiple MCSE's to keep it running.
Linux for Desktops, is a FULL Network suite, with Red Carpet to distribute software across the network PC's and easing in patch management, which there is very little of in a Netware world.
Linux for Desktops and NOvell Linux NOS is by far the most robust, affordable and complete network solution available today. I have set it up for a 15 node office a 30 node office and across 34 branches of a grocery chain in BC, it hasn't failed ONCE, not one single issue in over 9 months, no reboots, no extra hardware needed, the system requirements are VERY minimal it is just excellent all around.

Do yourself and your company a favour, your needs are small this will more than suffice as you grow but it is very affordable for small and medium sized businesses although Netware serves some of the largest corporations around the world. In Europe, Netware and Linux are taking over from Microsoft as people become less and less trusting of MS products. I have always installed Novell products, many times removing older MS installs to upgrade to Netware products, customers thank me and can't believe they were sucked into investing SO much in MS offerings.
Good luck,
