Volume Manager is a Mac OSX app used to organize, automate, and monitor the mounting of Windows (SMB) and Apple (AFP) volumes/shares/disks. Laptops can use this app to manually or automatically mount volumes at work and at home. Volume Manager can also be used to wake computers that are sleeping on an ethernet LAN.
Volume Manager holds a list of volumes (hard drives on other computers) with the necessary username and password and automatically mounts them whenever you want. Better still, it watches and makes sure that they stay mounted if the network status changes.
