Servicing and registering Machines on PXE Boot is convenient was to deploy Payloads to batches of (or individual) systems new to LSM and/or new in your organization.
Unbox and rack 1 or 500 servers and load them all with an initial OS of your choice, in minutes and with no manual intervention.
Unregistered Machines can be both Registered and Serviced with a Payload when the Configure page's "Machine: Netboot Actions" set to "Register and invoke selected Payload".
Warning: this is potentially a very distructive operation as any Machine that PXE Boots could have contents overwritten if you select a Payload containing a Deploy Snapshot or potentially-damaging RAM Agent Scripts.
