1. First, verify that the MTFTP service is running, and that the PXE Server and MTFTP services are set to manual. This could help prevent conflicts between services. Restart the PXE Config Helper service, which should restart the other three services in the correct order. Test your job at this point.

4. Delete all contents in WAIK folder in the eXpress share.
5. Reinstall WinPE files with the PXE Configuration utility by creating a new PXE configuration and clicking the "Add pre-boot" button. After creating a new WinPE configuration and letting the PXE Configuration utility save the new configuration to the PXE server, check ...\Program Files\Altiris\eXpress\Deployment Server\PXE\Images\MenuOptionNNN\X86PC\sources to verify that the boot.wim file exists with a new modification date.
6. Run a network trace (WireShark for example) to evaluate network packet traffic and identify problem sources.
7. Does the client computer have at least 512 Meg of RAM?
