When configure PXE Service Point in Microsoft System Center Configuration Manager 2007, booting may fail with the following errors:

PXE-T04: Access Violation
PXE-E36: Error Received from TFTP Server
PXE-M-F Exiting PXE Rom

You also may notice missing entries in the SMSPXE.log

Cause

To Configure DHCP Scope on Cisco Routers, add the following to DHCP Scope:

next-server ‘IP Address of PXE Service Point’
