We have an office with 4 computers and are planning to buy a server, but dont know which software is best.
Which of these are best for basic functionality and security;
1) Windows 2003 Server Standard
2) Windows 2003 Server Enterprise
3) Windows 2003 Server Datacenter
4) Windows 2003 Server Web
5) Windows 2000 Server
6) Windows 2000 Advanced Server
7) Windows 2000 Datacenter
8) Windows NT 4.0 Workstation
9) Windows NT 4.0 Server
Also what is the best way to backup onto a second hard drive. Can i get a PCI raid controller, and a second drive? will that do it?
