Recently I came across this error in a smsts.log where I work. OSD had been working fine until a few weeks back when it suddenly for no reason started to fail. Right after entering WinPE you get the message; “An error occurred while retrieving policy for this computer (0x80004005). For more information, please contact your system administrator or helpdesk operator”
At first i there was an issue with DNS since this is a common problem or that the time in BIOS was incorrect . Both, are quite common and I thought it was going to be a walk in the park to fix, but everything was correct. The time in BIOS was right and DNS lookup worked as it should.
Reading through the smsts.log showed the following errors:
This only shows that the boot was made with a USB-stick and not through PXE, but the next part showed the following:
This made me think, what could cause this problem, there were no errors in the network, I could access files and shares through the prompt in WinPE, and the time stamps were correct in the log. Then it hit me, the installation of SCCM was configured with HTTPS only and using a PKI for certificates.
The solution was to recreate the bootable media used to get a new and updated certificate in it. Using the newly created boot-media, everything worked as it was supposed to do!
This is only a solution if you are booting with a bootable USB-stick, for PXE, the issue could be completely different.
