We are looking at using SCCM to deploy our Operating Systems.
I have set a selection of machine up so that their first boot option is boot from network. This then looks for a pxe boot advertisement.
On our machines this takes about 10 seconds to work out that no adveretisement is available and carry on but at some of our sites on different VLANS and on slower connections this can increase startup times by 2 or 3 minutes not just the 10 seconds at the main site.
Our Director is not happy with this and does not want it to take more than 10 seconds or so. My question really is if we can distribute our OS images via multicast through the SCCM client without PXE booting? If it is possible will this in theory completely wipe the machine and build a clean machine or does it simply update the OS?
