Resetting the AWS Domain Controller Password

Hi,

We have been locked out of our domain controller server. This server is hosted on AWS. We have lost the key/value pair that was used to create the domain controller. As a result, we are unable to have access to the old domains in AD.

We have tried the following approach but have been unsuccessfully in getting the results we need: https://woshub.com/reset-domain-administrator-password-active-directory/ -> Section 'Resetting the Domain Admin Password on a Virtualized Domain Controller'

Is there any backend method to get to the Windows machine?

Thanks
