Your question is too broad as Windows 2003 server can be used for many purpose like:
- file server, printer server, VPN server, terminal server, domain controller
- DHCP server, DNS server, WINS server
This is just to name a few. So you can refer to Microsoft website to start for documentation and best practice:
