An external system that operates in a Windows environment to use the COM technology to request a service (generally an activity execution) of the your PRPC system. The COM object (an ActiveX control in a Windows Dynamic Linked Library) is created using Microsoft Visual Studio and a Service COM rule (Rule-Service-COM rule type).
Important: The rule type rule-service-COM is deprecated. As appropriate, migrate to Service dotNET rules.
