Now, in this article, we’ll see how to boot Windows Server in Directory Services Restore Mode (DSRM).
DSRM would be the only way to log in to a Windows Server, in case if you can’t login with AD. Also, when you boot into DSRM, the domain controller is taken offline. To login into DSRM, you can only use DSRM password. This is because the DSRM password used is for the local Administrator account. It is authenticated by the local Security Accounts Manager (SAM) database.
