TS Dell 760 TPM Actiavate error

Recommended Posts



I was successfully able to use the task sequence for Dell Optiplex 760 to enable TPM and activate the first time.

Now we are reimaging the machine and tpm will not activate.

I cleared the TPM and set it to deactivate mode. Nothing has changed in our environment or the task sequence


When cctk is trying to activate TPM i get an error "error in setting the value. Note: to set tpm - 1. admin password must be set, 2. tpm must not be owned and 3. tpm must be deactivated."


I tested it manually in task squence via command line and i still get the error


We do have a bios password and tpm is deactivated.


the nios has been update

using CCTK 3.1

SCCM 2012 r2 sp1



Any support would be appricated
