LestaG Posted July 4, 2013 Report post Posted July 4, 2013 I have an inherited environment and just trying to understand the PXE process Currently I: In SCCM Add computer manually in SCCM Add computer to collection to boot and reimage computer with XP image Go to computer, reboot and press f12 to PXE boot and f12 to start imaging The imaging actually goes to a MDT image screen (to select the image from MDT to use) My assumption ....is: The PXE server checks to see if there is a SCCM advertisement for the computers MAC address, if there isn't it passes it on to MDT to give the computer an image. A few hours later if you boot the PC and f12 the SCCM image is sucessfully loaded. I am assuming that it takes a few hours for "all" of SCCM to know it exisits? Is this "normal" behaviour for MDT to be the fallback image option? cheers Lesta Quote Share this post Link to post Share on other sites More sharing options...
Jorgen Nilsson Posted July 4, 2013 Report post Posted July 4, 2013 Hi, No and no. It is normal to boot to MDT if SCCM fails, Did you try to boot the computer from SCCM Before you imported it and added it to the Collection? THen the PXE cache could cause the issue. http://sccmcorner.blogspot.se/2012/03/i-had-issue-with-laptop-that-was-loaded.html Normally I use Unknown computer support so that if the computer doesn't exist in SCCM it is treated as a "unknown" device and can boot anyway:http://technet.microsoft.com/en-us/library/cc161877.aspx Regards,Jörgen Quote Share this post Link to post Share on other sites More sharing options...
