Random 6743 TPM password missing error. RRS feed

  • Question

  • Not very often but once in a while MDT ends with 6743 error, TPM password missing.

    At the desktop, I simply need to click activate Bitlocker and then a key is produced in our AD.

    The BIOS is set up the same every time, only this issue is a random thing. It does have the supervisor password
    set in the BIOS and we don't even touch anything in TPM in the BIOS.

    Just wondering what this is about. I see someone added

    TpmOwnerPassword=Pa55w0rd

    in their CS.INI but I'd just rather not.

    Any ideas would be helpful.

  • Hey Sir, did you figure this out? I am having the same issue and also don't want to update the CS.INI.

  • I indeed did end up adding

    TpmOwnerPassword=Pa55w0rd

    into my CS.INI and now my summary screens are white and not yellow with the error about a missing
    TPM password missing. Since MININT folder gets deleted I suppose it's safe to add this to my CS and besides,
    it resolved my issue.
