What if any enterprise or mission critical applications are you running? Do any of your applications require a back-end SQL database server? If so, what is the DB Server/Version?

What kind of hardware (make/model) of server do you have? How much/what kind of storage and memory is this server configured with?

I hate to answer a simple question with 20 MORE questions, but an informed suggestion about which MS Server OS to purchase really depends on your user-load, networking and application environment. I currently use SBS 2003 in a small office environment (7-10 PCs, 10-15 users, website, email, SQL-based enterprise application) and it works well for me running on a Dell PowerEdge Xeon server with 3-GB RAM and a 3-drive hardware RAID array. More demanding environments with more PCs, users, applications, etc. will require a different version of MS Server and higher-end hardware, storage, networking, etc.
