What must be done to rename an existing site in Active Directory?

To rename an existing site in Active Directory, the most straightforward method is to right-click on the site and select the Rename option. This process is designed to allow administrators to easily change the name of a site without needing to take additional steps, such as deleting and recreating it. The renaming functionality is embedded in the Active Directory Sites and Services management tool, ensuring that all associated attributes and configurations remain intact during the process.

While modifying the properties settings may seem like it could lead to a name change, it typically refers to other specific attributes rather than directly renaming the site itself. Using a script may be a valid approach in some environments, but it's usually not necessary for a simple task like renaming a site, making it less efficient. Deleting the site would also result in loss of configurations, which is not the desired approach when simply renaming the existing site. Thus, the method of right-clicking and selecting Rename is the most efficient and effective way to achieve this task.
