PENDING PXE boot hangs at UnlockToken.pol with white screen

[IanW]

Hi all,

I have an issue with SCCM PXE boot where it hangs 4 times out of 5 at "TFTP: 10.217.10.63: request for EFI\Microsoft\Boot\Policies\UnlockToken.pol." and just displays the white SCCM screen, it then eventually reboots, after a random number of attempts it eventually pops past that and then brings me to the SCCM password screen for OSD.
NIC Drivers are added to boot image, SCCM version is 243 Hotfix Rollup.

Any pointers with how I can get it to PXE every time straight in?
Many Thanks

Ian

Are you using WDS? If yes, switch over to PXE responder service. Coming to your issue, it looks like either the device is not contacting the management point to get the policy or the device has problems in getting the IP address from the DHCP service.

Thanks Prajwal, I moved over to PXE Responder Service last week after reading one of your posts, I will take a look at your suggestions, all machine sit on the same flat network so I can't see why they would have a problem with receiving data.

Just to confirm, you don't even get to the screen where it load the TS correct? The PXE boot fails immediately?

No it gets all the way to the end apart from flicking into the SCCM password box:

Alright, i guess the smsts.log file should be created on this problematic client. Check that.
