PXE environment - relay or dhcp options
Hi, What is nowadays the best practice for OS deployment through a PXE environment in different subnets? Situation: - Server subnet & Client Subnet - Clients get deployed in the client subnet - DHCP and PXE are located in Server subnet Both subnets are separated by a Juniper Firewall/Router So to deploy new systems we have two possibilities: - Add DHCP options with extra options for a PXE env. - Configure PXE server as extra DHCP relay (so in fact PXE relay) on the Juniper. Thanks!

Hi, DHCP Relay is always best practice and I always use it and it works great. I recommend that you use IP Helper/Relay. More information: "An alternative to using IP Helpers is setting DHCP Options on the DHCP server, specifically DHCP Options 60 (PXE Client), 66 (Boot Server Host Name), and 67 (Bootfile Name). However, DHCP Options can be problematic and may not work reliably or consistently. Furthermore the use of DHCP Options to control PXE requests is not supported by Microsoft. Therefore the only recommended and supported method of PXE booting client PCs that are on a different subnet than the DHCP or WDS/PXE Service Point servers is the use of IP Helpers." http://blogs.technet.com/b/configurationmgr/archive/2011/01/05/troubleshooting-the-pxe-service-point-and-wds-in-configuration-manager-2007.aspx Regards, Jörgen -- My System Center blog ccmexec.com -- Twitter @ccmexec
