Microsoft DCOM
Port 1029 is frequently associated with Microsoft Distributed Component Object Model (DCOM) communications. DCOM enables software components to communicate directly across networked environments, predominantly within Windows operating systems. While this port is unofficial and dynamic, it's commonly observed during remote procedure calls and system management activities..
Microsoft's Distributed Component Object Model (DCOM) is an extension of COM that supports communication among objects on different computers across a network. It enables distributed applications, facilitating interoperability between software components running on separate machines. DCOM is primarily used in enterprise environments for remote management, automation, and system-level communications.
When applications use DCOM, the initial connection often occurs via TCP port 135 (RPC Endpoint Mapper), which negotiates dynamic ports for further communication. Port 1029 is among these dynamically assigned, ephemeral ports. As a result, DCOM traffic may intermittently utilize 1029 during normal operations such as Windows Management Instrumentation (WMI), remote administration tools, or system monitoring services.
Due to its dynamic nature, port 1029 is not consistently assigned or documented as an official endpoint. Nonetheless, it remains relevant in network traffic analysis to identify remote management activity, system level communications, or potential misuse of the DCOM infrastructure.
