Description

• TPM has been disabled from the BIOS and on boot I was presented with a challenge for a Recovery Key.
• The Key provided does not match when I enter it into N-able N-central .

Environment

• N-able N-central 12.2 SP1 and later.
• Disk Encryption Manager

Solution

• When TPM is disabled from the BIOS, Microsoft considers this to be the same as changing out a hard drive.
• As a result, it will not release the key used by TPM.
• To continue, please run the Disk Encryption Report from N-able N-central to be provided with the correct Recovery Key to enter on the device.
  • Manually retrieval from the N-able N-central UI will not work in this situation.
