Abstract
A method and system for managing a secure network boot of a secondary server (server blade). The server blade sends a request, via an Ethernet switch, for a boot program to multiple Dynamic Host Configuration Protocol (DHCP) servers. One of the DHCP servers responds with an address of at least one Pre-boot Execution Environment (PXE) server that can upload a boot program to the server blade. Only if the responding DHCP server is on a list of known trusted DHCP servers will the Ethernet switch allow the server blade to receive the response from the responding DHCP server, thus allowing the download of a boot program from a PXE server.
