My environment is:server 2003 sp2sccm sp2wsus 3.0 sp2I am trying to enable unknown computer support with the PXE service point properties and unfortunately that check box is not available?Does this option work with server 2003 or do I need server 2008?I tried uninstall the PXE service point and WDS, restarted the server. Then I reinstalled WDS, restarted, reinstalled the PXE service point, restarted and the check box is still not available.

To enable unknown computer support you need SCCM 2007 R2.See also here: http://technet.microsoft.com/nl-nl/library/cc161883(en-us).aspxMy Blog: http://www.petervanderwoude.nl/

thank you for your reply. I installed SCCM SP2 with came out after R2.Frank

you still need R2 installed to enable unknown computer support, Sp2 by it's self isn't enough, cheers niall My step by step SCCM Guides Follow me on Twitter

Niall,thanks for your reply. OK maybe I do not understand something:I installed:SCCMSCCM SP1SCCM SP2Where does R2 fall into the mix?ThanksFrank

Hi Frank,R2 is a separate download (22 MB), that you can download at http://licensing.microsoft.com.R2 requires SP1 or SP2 and you need to have software Assurance in order to use it. Read all about R2 here:http://technet.microsoft.com/en-us/configmgr/cc761485.aspxHopefully this answers your question.Ronni Pedersen | MVP | MCTS:Configuration Manager 2007 | MCITP:Enterprise Administrator | MCT

Ronni,thanks for the reply and clearing up this for me. OK, I have SCCM sp2 and now I just the R2. My office says the download is not here. Has anyone downloaded the file yet from MS? what is the file name or listing for the file? I do not have access to download the file from MS.ThanksFrank

the file details should be similar to below: System Center Configuration Manager 2007 R2 (x86) - DVD (English) Includes: Other; 10/14/2008 File Name: en_system_center_configuration_manager_2007_r2_x86_dvd_x15-18165.iso Date Posted (UTC): 10/13/2008 5:30:42 PM ISO/CRC: 2834A38F SHA1: EB57030A78C051C6A32DFDDDCF91F11AC4C6E3A8 Available to Levels: VS Pro with MSDN Premium (Empower); Developer AA; MSDN Universal (Retail); VSTS Team Suite (VL); VSTS Architecture (VL); VSTS Development (VL); VSTS Test (VL); VS Pro with MSDN Premium (VL); MSDN Universal (VL); VSTS Database (VL); VS Pro with MSDN Premium (Retail); VSTS Test (Retail); VSTS Development (Retail); VSTS Architecture (Retail); VSTS Team Suite (Retail); VSTS Database (Retail); BizSpark Admin; BizSpark; My step by step SCCM Guides Follow me on Twitter

thanks. They downloaded the file this morning. I installed the R2 on server 2008 with SQL 2005 and there is no support for multicasting or unknown computer support. Am I missing a configuration required?Thanks for your help.Frank

Below is the file name that was downloaded from MS:SW_DVD5_Sys_Ctr_Config_Mgr_Svr_2007_R2_English_CM_07_R2_Rel2_MLF_X15-18165.ISO

OK, it must be Friday since the first install I did the splash.hta with no luck. So, why not try the CONFIGMGR2007R2.MSI and wow, multicast support. I cannot wait to try this out on some HP DC7900 computers!!!Thanks for all of you helpFrank
