[CentOS] Getting Samba to work in CentOS 4.4

I'm trying to access files on a networked Windows machine from my linux
box (CentOS 4.4) using SMBFS mounting but it doesn't work. I've checked
the Service Configuration and there's no sign of the smb entry in the
list. Do I have to install this additionally and if so how, as I thought
it would be installed as part of the standard workstation package?
