## Overview

This section is for administrators of Business Central on-premises. It has two pages: a how-to page that explains the ways to change server configuration, and a reference page that lists the settings themselves.

Start with "Configure Business Central Server". It describes configuring an instance after installation using Setup, the Set-NAVServerConfiguration PowerShell cmdlet, or by editing the CustomSettings.config file. It also covers restarting the instance and managing settings that can be updated dynamically. It applies to 2022 release wave 2 (version 21) and later.

Then use "Business Central Server instance settings" to look up individual settings. It covers server topology, database connections, multitenant deployment, service defaults, sign-in security, certificates, encryption, Azure Key Vault and Microsoft Entra integration. It also covers file access, code execution, data sharing, HTTP client behavior, database writes, file operations, client endpoints, web services (SOAP, OData, API), API subscriptions, throttling, administration services, extension deployment and debugging. The page refers to specific versions, from version 20 through 27.4.
