Register the Windows Admin Center gateway before enabling Azure integration

Source facts

Microsoft requires Azure registration of a Windows Admin Center gateway before it can use the documented Azure integrations. The registration is retained when the gateway is updated. Only a gateway administrator can perform the registration. The guided process creates a Microsoft Entra application in the directory, and the gateway’s Azure settings provide a link for inspecting that application in the portal. Microsoft documentation.

Applicability

Identify the gateway, Azure tenant, administrator, intended integration, and existing registration. Review whether the gateway was migrated or previously registered before starting another registration workflow.

DSE recommendation

Have the gateway and identity owners agree on the intended tenant and application identity. Record the registration’s purpose and the owners responsible for maintaining it. Use the approved administrator account and preserve the existing settings before changing the integration configuration.

Verification

Inspect the resulting Entra application and compare its tenant and identifiers with the approved record. Test the intended integration with a representative authorized user and check the gateway’s retained registration after an approved update. Resolve an unexpected application or tenant association before enabling additional Azure features.
