This has been bugging me for a couple of weeks now and i cannot seem to fix it.

I have a couple of machines at my desk (optiplex 9020) And i cannot image them with anything, I get the following error  in the SMSts.log

VerifyContentHash: Hash algorithm is 32780	ApplyOperatingSystem	8/18/2015 1:42:15 PM	1604 (0x0644)

The Hash mismatch does not happen on other machines. Just there 2 optiplex machines at my desk. Both machines have the same exact hash error (including the actual hash)

To attempt to fix the issue I have:

• Redeployed and verified content on the DPs,
• Remade the OSD task sequence. 
• Re imported the image file changing the name and the image location
  
• Re-made the boot image
• Re-imported the NIC drivers
• Switched out HDD/SSD, and ram, and ever the mother board, on the problem machines.
• Newest BIOS is installed. as well as all default BIOS settings.
• Tried a Windows 8.1 task sequence
• Rebooted the Main server, as well as the local DP

I have tried everything i could think of. This used to work fine a couple weeks ago, it still does. Just not on the optiplex 9020. I have tried this on 2 different optiplex 9020 machines, and do not have a third one to play with.

Any clue? I am gripping at straws here.

If you set the OS to run from DP do you get the s
