What is COM+ Network Access?
COM+ Network Access is a technology that allows COM+ applications to communicate with each other over a network. This makes it possible to create distributed applications that can run on different computers.
COM+ Network Access is based on the Distributed Component Object Model (DCOM), which is a Microsoft technology that allows COM objects to communicate with each other over a network. DCOM provides a way to marshal COM objects, which means that they can be sent across a network and then unmarshaled on the receiving computer. This allows COM objects to be used in distributed applications.
COM+ Network Access provides a number of benefits over DCOM, including:
- Improved performance
- Increased security
- Simplified development
