you need a service called
Samba or
SMB (server message block)
the configuration file is
/etc/samba/smb.conf (there is an example in that directory, you can copy it and use it as a base, it is quite documented)
the startup script is
/etc/rc.d/rc.samba
and here's a couple o' links to make your reading

in order to work with Samba or any other network service, you need to make sure those machines are networked with some
pings
