Communication Services
The following services are used by HP Insight Remote Support for one or more of the following tasks: Remote Device
Monitoring (Device Discovery and Event Notification); Remote Data Collection; Remote Device Access.
DCOM
The Distributed Component Object Model (DCOM) is a Windows protocol that enables software components to
communicate directly over a network. Previously named "Network OLE”, DCOM is designed for use across
multiple network transports, including Internet protocols such as HTTP and WMI (Windows Management
Instrumentation).
DCOM allows processes to be efficiently distributed to multiple computers so that the client and server
components of an application can be placed in optimal locations on the network. Processing occurs transparently
to the user because DCOM handles this function. Thus, the user can access and share information without
needing to know where the application components are located. If the client and server components of an
application are located on the same computer, DCOM can be used to transfer information between processes.
ELMC
The Event Log Monitoring Collector (ELMC) is a proprietary management service included with Insight Remote
Support. ELMC is platform-specific and provides error condition detection on the monitored endpoint system on
which it is installed. It communicates these events to Insight RS on the Hosting Device, which can be running
either on the same system as the ELMC system or another system on the same TCP/IP network. Different ELMC
packages exist for the same ELMC version, depending on the operating system and hardware platform.
ESP
Encapsulating Security Payload (ESP), or IP protocol 50, is a protocol header inserted into an IP datagram to
provide data encryption and authentication. Remote Device Access uses ESP in tunnel mode to establish VPN
connectivity. ESP is described in RFC 4303.
