Easiest is to use profile manager if you have that set up. If not then the long hand way on each mac is as follows:
In the finder menu of the mac choose go>connect to server. Then type in smb://(full path of the share you want). Click connect and it mounts on the desktop. Then open System preferences>users and groups and go to the log in items tab. Drag the icon of the share from the desktop to this window. Log out and it should then mount on the desktop each time. If you use screen sharing on the mac and the others macs are accessible via a network you can do all from one mac. (Screen sharing is in system>library>coreservices>applications).
