spgsitsupport Posted August 22, 2015 Report post Posted August 22, 2015 I do trying not to use Unknown Computers for PXE boot, but create computer account in SCCM (MAC & BIOS GUID, correct collection), so it boot with the image that is assigned to this collection. Works fine. But once the SCCM client gets installed on the machine & it registers itself with SCCM, but a completly different object gets created with EXACTLY same name, but different GUID Quote Share this post Link to post Share on other sites More sharing options...

spgsitsupport Posted August 24, 2015 Report post Posted August 24, 2015 I have retested my syspreperd image. Removed smscfg.ini & certificates. Removed Computer object (from my previou try) from SCCM. Re-created pre-staged computer object with MAC & GUID (from PXE boot screen 421... ) Machine boots to desired PXE boot image Machine gets re-registered with SCCM with different GUID to the prestaged object (exactly same as per first post 9DA... ) Name & MAC address of the "new" registered machine are identical to the prestaged computer object (only GUID is different) It makes no sense to me...

spgsitsupport Posted October 3, 2015 Report post Posted October 3, 2015 In the pictures above the BIOS GUID is (each part) in reverse order. Why is that? It explains why the manually created object is "different" then SCCM registered machine. I expect that if manual creation was in reverse order then the object would be re-used Seb Quote Share this post Link to post Share on other sites More sharing options...
spgsitsupport Posted October 7, 2015 Report post Posted October 7, 2015 Sadly no matter what I do, the objects gets re-created in SCCM with IDENTICAL GUID Quote Share this post Link to post Share on other sites More sharing options...
spgsitsupport Posted October 21, 2015 Report post Posted October 21, 2015 Nobody noticed this same? Nobody using it this way? I have now tried number of times & the end result is always the same, DUPLICATION of the record Seb Quote Share this post Link to post Share on other sites More sharing options...
