Built-in domain administrator account with old password (180 days)

Question

Built-in domain administrator account with old password (180 days)

Khushboo Kumari 20

Hello Experts,

I’m looking for the best approach for password rotation of the built-in Administrator account.

We have CyberArk in our environment. For password rotation, would it be better to manage the password rotation entirely through CyberArk, or should we schedule password resets at defined intervals and reset the passwords using scripts or manually?

Is there any other recommended approach for managing and rotating the built-in Administrator password?

What would be the best practice for securely rotating these passwords while ensuring that the accounts remain manageable and available when required?

Any recommendations or best practices would be appreciated.

Hello Khushboo,

Since you already have CyberArk, I would avoid maintaining a separate manual or scripted password-rotation process for the same privileged account. Having two systems changing the password can cause synchronization problems and makes auditing more difficult.

For the built-in domain Administrator account, a privileged access management solution such as CyberArk can manage password rotation, provided it is configured and validated according to your organization's CyberArk policy. A 180-day unchanged password is generally a long interval for a highly privileged account; however, the appropriate rotation policy should be driven by your PAM controls and risk requirements rather than an arbitrary manual schedule.

A few important practices are to keep this account for emergency/recovery use rather than routine administration, monitor its use, restrict where it can sign in, and use separate named administrative accounts for normal privileged work. Also make sure there is a tested recovery procedure in case CyberArk itself is unavailable.

If instead you are referring to local Administrator accounts on member servers/workstations, Microsoft Windows LAPS is the Microsoft-native solution for automatically generating and rotating unique local administrator passwords. It should not be confused with management of the domain's built-in Administrator account.

So in your environment, I would use CyberArk as the single password-management authority for the domain Administrator account, rather than adding scheduled scripts or manual password resets alongside it.

Hi, thanks for the information, but what if Cyber is not working because CyberArk is a 3rd party tool and managing the built administrator account password is concerning when we are using it as a break glass account

Hello Khushboo,

That is a valid concern. If the built-in domain Administrator is intended specifically as a break-glass/disaster-recovery account, making CyberArk the only way to retrieve or manage its credential creates a dependency on CyberArk being available during the emergency.

Microsoft recommends reserving the built-in domain Administrator account primarily for initial build and disaster-recovery scenarios, securing it heavily, restricting where it can sign in, and monitoring any use or password changes.

For this scenario, I would separate the break-glass design from normal privileged-account management. Keep normal administrative accounts managed through CyberArk, while ensuring the emergency Administrator credential has a documented recovery method that remains accessible if CyberArk, AD-integrated services, or normal management infrastructure is unavailable. Microsoft similarly recommends that emergency credentials be stored securely and that emergency access not depend on the systems whose failure you are trying to recover from.

Whichever design you choose, the built-in Administrator account should not be used for routine administration. Its recovery procedure should be tested periodically, and any sign-in or password reset should generate an alert. Microsoft Defender for Identity also specifically identifies built-in domain Administrator accounts whose passwords have not been changed for more than 180 days as a security exposure.
