I have an HP 8440p that is using PXE boot and will bring me to the Altiris 7.5 Initial Deployment Menu screen, and will deploy Windows 7 with no problems. However I have another HP 8440p laptop and it gives me the pxe-m0f exiting intel boot agent error message
what happens if you don't know the old computer name, how can you find what the DNS name was so that you can remove the agent from the console http://www.symantec.com/connect/forums/pxe-boot-failure
Found the solution...needed to search for the MAC Address in the Console and delete it.
Change the filter to look for MAC Addresses.
Attached a snapshot below of how to edit the criteria for MAC address
