Technical Details

what runs on :5725

The service uses TCP port 5725 for its resource-management endpoint, exposed as a Windows Communication Foundation (WCF) SOAP service. Common FIM configurations use an HTTP endpoint such as ResourceManagementService on this port; the separate synchronization service is commonly associated with TCP 5726. Exact endpoint and security configuration can vary by product version and deployment.

security overview

This is an administrative identity-management API, so access could expose or alter sensitive identity data and workflows. Keep it on trusted internal networks and restrict access to authorized FIM clients and servers; do not publish it to the internet. Common configurations use HTTP on this port rather than TLS, so protect traffic with network controls or configure suitable transport security.
