My SCCM 2007 R2 installed on virtual Windows Server 2007 R2 Hyper-V machine. I've installed PXE role and WDS on this machine. DHCP was installed on other server (It's my domain controller). Need I configure DHCP options for PXE installation (for example, options 60, 66, 67) for OS deployment if I use Windows Server 2007 R2 on both machines?

If they clients are on the same subnet as the WDS Server you shouldn't need them as this is broadcast traffic. If you want to use WDS in other subnets as well you either need to configure DHCP Options 66 and 67 or configure IP helper on your Switch/Router.

Thanks, Maik. At the moment I'm going to use OSD in local subnet but in future I need to use it in remote subnets.

Hi Maik, I am in a process of configuring SCCM OSD in my environment. I have read so many blogs and the microsoft article which says not to configure optins 66 and 67 on DHCP Server as a best practice and recommends to configure IP helper on Router.Could you please throw some light on following points: 1. Please explain in brief about the process flow, like how a client know to go where step by step to get all the info of options 60,66 and 67. 2. how to configure these settings on a router if possible. Any Idea please.. Regards, Ankur

Thanks for your reply tesgroup! Could you please also help me out where to set option 60 in DHCP Server (Windows 2008 R2) if we have DHCP and WDS reside on the same server. Also can you please let me know how this flow works like: 1.When a client boots up, where it sends the first request for whom and for what. 2.how SCCM clients gets the information to contact on option 66 and 67 Regards, Ankur

Hi Ankur, you can check out these: http://technet.microsoft.com/en-us/library/cc771734(WS.10).aspx http://technet.microsoft.com/en-us/library/cc725614(WS.10).aspx you could set option 60, 66, 67 etc on the DHCP server global options, or you could set them per-scope. DHCP & PXE "share" the same ports/options, so they have to work together. in a network where DHCP & PXE are both used, modern client NICs will issue a DHCP Discover during the PXE boot, and the NIC will ask for PXE option information to be provided. DHCP will respond with a DHCP Offer that includes the options you configure. some systems may process the DHCP Offer as a referral and issue another DHCP Discover to the WDS. remember that DHCP, PXE are based on BOOTP - all of these are broadcasts, and that does not cross a router. So the DHCP and/or WDS must be on the same network segment as the requesting client, or, you need DHCPproxying or ip-helper, to forward the broadcast onto a remote DHCP/PXE etc.Don
