How to change the Default First-Site-Name in Active Directory

change Default First-Site-Name

It’s worth re-emphasizing that the first domain controller in a forest, a default site (Default-First-Site-Name) is-created in AD DS. As long as this site is the only site in the directory, all domain-controllers that you add to the forest are assigned to this site. However, if your-forest will have multiple sites, you must create subnets that assign IP addresses-to Default-First-Site-Name as well as to all additional sites. Please see this guide for how to set up VMs in Hyper in order to have Domain Controllers running on Virtual Machines, and “Post OS configure Windows Server 2019 Properties, and how to Setup and configure a DC.
