I have set up a workgroup network but it is not secure enough so I am thinking of using a domain instead. The problem isI don't know whether to use Small Business Server 2003 or Windows server 2003 as my operating system for the server computer?

Hello nreed323, choosing any edition of both SBS 2003 or Server 2003 is dependes on the size of your network , and services are required on this network. so, if you have a small network and just need to install a directory service "Active Directory" you can install windows SBS 2003 but put in ur mind it have a limited feature. for more info you can see the FAQit will give you all inforamtion about SBS 2003 feature and what u can use what u can't ? but if you have a mid/large or even a small networkbut u want to be able to install any services or a special software without limited features ,something like ISA 2006 that's not supported by windows SBS 2003 - see the FAQ - i recommend using Windows Server 2003,Standard Edition , it will very powerful.
