What is the quickest method to push out an internal certificate to all workstations in an Active Domain?

The most efficient method to distribute an internal certificate to all workstations within an Active Directory domain is through Group Policy. Group Policy allows for centralized management and configuration of operating systems, applications, and user settings within an Active Directory environment.

Using Group Policy, administrators can create a policy that automatically deploys the certificate to all designated computer objects in the domain. This ensures that all workstations receive the certificate without requiring manual intervention on each individual machine. Moreover, Group Policy can enforce the installation, ensuring compliance and proper trust management across the network.

While local policy can be used to install certificates on a specific machine, it does not scale well to multiple workstations, as it would require manual configuration on every single device. Logon scripts could theoretically be used to deploy a certificate, but they are not as reliable or secure as Group Policy and can introduce complexities in management and troubleshooting. Windows Update is not a suitable choice for distributing certificates since it is primarily designed for operating system updates and patches, not for managing internal certificates.

Therefore, using Group Policy is the most effective and streamlined approach to pushing out an internal certificate across all workstations in an Active Directory domain.
