    BITLOCKER - Unable to clear/reset TPM


      Good morning.

      I was trying to set up bitlocker on my Dell XPS 15 running Win10 Enterprise. After running the Bitlocker wizard on C: I got this error: “The TPM is defending against dictionary attacks and is in a time-out period”. So I opened the TPM MMC and I saw that all the options in the action menu are blanked out except for “Prepare the TPM”. Unfortunately when I click on it I get another error: “The TPM on this computer is currently locked out”.

      I also tried clearing it in the BIOS but again, the option was blanked out.

      What can I do to resolve it?
