Hello, I've been using WDS on Windows Server 2012 R2 for quite a while now, and mostly in success.
However, yesterday the boot image that I use to boot x86 Windows 8 Client hardware (Lenovo TP10) suddenly gets a
'Secure Boot
Image failed to verify with *ACCESS DENIED*'
Message each time i boot it. This does happen on 4 of these specific deviced; if I try booting to my x64 image on a Fujitsu E544, it works like a charm.
The reason why I say 'Suddenly stopped' is because it did work without problem (on all devices on which it does no longer..) untill yesterday evening.
I did not change anything in the configuration; except that I tried using the boot image to create a 'Capture Image' - which failed because it is a modified boot image and the WDS Capture Client was not found inside it.
Directly after that; this behaviour started.
I've enabled logging in the 'Event Viewer > Application and Services --> Microsoft --> Windows --> Deployment-Services-Diagnostics-->Debug' and it gives me 133 events while booting, from which 3 are errors:
[Information]
[WDSServer/WDSTFTP] TftpSession[0x000000E5957068F0:192.168.48.8:1433] - Error: Received error from client. Code=8.
[Error1]
[WDSServer/WDSTFTP] [base\eco\wds\transport\server\tftp\tftpsession.cpp:1636] Expression: , Win32 Error=0x4d3
[Error2]
[WDSServer/WDSTFTP] [base\eco\wds\transport\server\tftp\tftpsession.cpp:1720] Expression: , Win32 Error=0x4d3
[Error3]
[WDSServer/WDSTFTP] [base\eco\wds\transport\server\tftp\tftpserver.cpp:1211] Expression: , Win32 Error=0x4d3
I am unable to find 0x4d3 anywhere as a consistend error message (well, I can find that it is being logged a lot, but never a meaning of it)
As I check the security of the file which is downloaded before the errors start (according to log)
[WDSServer/WDSTFTP] TptReadFile: File=W:\RemoteInstall\boot\x86\wdsmgfw.efi, Size=1286608
It says 'Everyone' can read and execute; and it is not different from the wdsmgfw.efi in the x64 folder (x64 bootting works)
The signatures seem to be OK (digitally signed 'till 04-30-2015) by microsoft)
and my date/time settings also seem to be correct (else the x64 won't work either)
I tried creating a new x86 Windows 8 boot.wim, and uploaded it without modifying it, and the problem still exists.
I'm really desperate for a solution, cause reïnstalling the WDS feature would be a major pain and I do need this solution to image x86 Windows 8 machines with WDS.
Thanks in advance,
Alex van den Bos
