I have few computers which I am trying to get the bitlocker enabled with TPM enabled and running into error even though TPM is enabled.
Following has been done:
Changed to PTT in bios
Secure boot is on
Bios is set to UEFI only
Bios is updated to latest version from manufacture
Did Clean install windows 10 latest version as of 09/28th
Harddrive is GPT format.
TPM 2.0 is enabled and verified by tpm.msc
After login into computer as domain admin, I can see "prepare the TPM is grayed out". Clear the TPM is available.. Cleared the TPM but still same error.
CMR is disabled
Also under system information I am seing the following statement "Device Encryption Support Reasons for failed automatic device encryption: PCR7 binding is not supported, Hardware Security Test Interface failed and device is not Modern Standby, Un-allowed DMA capable bus/device(s) detected"
