Essentials at a Glance

Small-Office Server Setup Checklist

1. Size the hardware — 2 processors maximum. Allow 16 GB RAM and SSD storage for a comfortable file and AD server.
2. Plan your domain name — use a subdomain you own, such as ad.yourcompany.com, rather than .local.
3. Install and activate Essentials using the steps below.
4. Add roles — Active Directory Domain Services, DNS, DHCP and File Server.
5. Set up backups — Windows Server Backup to an external drive or NAS, plus an off-site copy.
6. Manage it remotely with Windows Admin Center from any browser on your network.

Important: Windows Server 2019 Essentials no longer includes the "Essentials Experience" role from earlier versions: the dashboard, client PC backup and Remote Web Access. It is the full Windows Server operating system with Essentials licensing limits. Plan to use standard tools such as Windows Admin Center and Windows Server Backup instead.

How to Install and Activate

1. Install Windows Server 2019 Essentials from Essentials installation media.
2. Open an elevated Command Prompt and run slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX, then slmgr /ato. You can also go to Settings → Update & Security → Activation.
3. Activation is online, so make sure the server is connected to the internet.
