PSP Role in SCCM & WDS issues

Hey ,


 I already wrote a previous blog post about this marverlous problem that al the sudden you can’t boot anymore from PXE . It says PXE-T01 No boot File found . If you dig deeper into the c:\windows\temp folder there is a  hidden PXEBootfiles folder to see…


The problem were goofy ACLs on the c:Windows\temp\pxebootfiles. When I attempted to revised security, I got an Access is Denied message. Once the above directory was deleted, the SMSBoot folder would populate when the bootimage was refreshed on the PXE point. If you get this error, you need to locate the folder (it is hidden), take ownership of it, and delete it. The folder will be at %temp%/PXEBootfiles.


 This worked BEFORE SCCM SP1 !!


 After I applied SP1 @ customer site , it did not work … What the hell ?


 The solution was simple & logic , but hard to find out why  :


If you put an operating system image an select the SMSPXEIMAGES$ Distribution point instead of the normal Distribution point , you will receive an access denied error and the ownership on the %temp%/PXEBootfiles is taken by a goofy SID account that does not resolve. The error occurs because the permissions from the WIM file are applied to the PXE temp folder used for extracting binaries, and the logged in user does not have permissions to delete those folders. Therefore, the PXE service point fails to extract binaries because it cannot delete or access the temp folders for extracting purposes.


Make sure that you do not have an OS Image or OS Package being distributed to your \\YOURSERVER\SMSPXEIMAGES$ ! After this step you need to locate the folder (it is hidden), take ownership of it, and delete it. The folder will be at %temp%/PXEBootfiles.Restart the WDS services and the SMSBoot folder would populate automaticaly.


PXE boot will work again!
