I deeply apologize for the delayed answer for this matter, thread may have sneaked between our queue, still no excuse :/
In this case, I have some things to be checked:
1. Have you checked this link? https://technet.microsoft.com/en-us/library/dd851452(v=ws.11).aspx
2. Is there a way you can disable one of the encryptions (hw or software) to see the behavior of the system.
About the time for the TPM to ignore the password after lockout, the research didn't provide me with that infor, have you checked with Microsoft directly?
It would also be good to check with them if using both hardware and software encryption can affect the behavior of bitlocker.
Please let me know how it goes.
Looks like we are both busy, sorry for the delay.
I tried to reset the tpm 4 days later, and it still would not work due to being in a dictionary attack lockout.
#1. I had looked at that link and many more. The problem is that Microsoft says the TPM is controlled by the hardware vendor. Intel or the TPM manufacturer say the lockout is controlled by Microsoft.
There is no setting in windows to set how long the TPM dictionary attack in TPM 2.0 will last. It's up to the hardware vendor, but information on what this timeout period is eludes me. All I want to know is how long the lockout is so I can wait that long, and reset my TPM with the lockout key. Microsoft will not have this information, it's a hardware function.
#2. I cleared the TPM and reset the TPM that way. Of course that's dangerous if I forget I have encrypted data that I forgot to decrypt. I'm working now, I just want to know in cases of TPM lockouts, where the TPM ownership key is ignored, how long do I have to wait to try the key again.
I have actually seen this issue on other TPM chips as well. I haven't seen a reason for this so far, but a TPM Reset Lockout will not work even with the OwnerAuth Hash. The only way I have resolved this is by performing a Clear of the TPM after disabling the Bitlocker protectors on a device, restarting, initializing the TPM and then re-applying the Bitlocker protectors. Someone with knowledge on TPMs and why a dictionary attack blocks maintenance on the chip, without showing any lockout attempts would be appreciated.
