This security policy reference topic for the IT professional describes the best practices, location, values, policy management and security considerations for this policy setting,
Reference
This policy setting determines whether the Administrator account password must be provided before access to the computer is granted. If you enable this setting, the Administrator account is automatically logged on to the computer at the Recovery Console; no password is required.
The Recovery Console can be very useful when troubleshooting and repairing systems that cannot be restarted. However, enabling this policy setting so a user can automatically log on to the console is dangerous. Anyone can walk up to the server, shut it down by disconnecting the power, reboot it, select Recovery Console from the Restart menu, and then assume full control of the server.
Possible values
Enabled
The Administrator account is automatically logged on to the computer at the Recovery Console; no password is required
Disabled
Automatic administrative logon is not allowed.
Not defined
Automatic administrative logon is not allowed.
Best practices
- Set Recovery Console: Allow automatic administrative logon to Disabled. This requires a user to enter a user name and password to access the Recovery Console account.
