domain vs workgroup...

Can I set up a server in a workgroup type environment & share files, control
access to files, etc., just like in a domain environment?
I have a client who has 15-20 XP Home machines & has finally decided that
they need a server, as sharing files between 15-20 computers has become
quite a hassle!
