What is rpcapd.exe?

The genuine rpcapd.exe file is a software component of Remote Packet Capture Daemon by Riverbed.
WinPCap is a packet sniffing tool that provides access to link-layer networks for Windows machines. Rpcapd.exe is part of the WinPcap packet library. This is not a critical Windows component and can be removed if known to cause problems. WinPCap provides programs the ability to capture and transmit network packets by bypassing the protocol stack. It also includes additional features such as support for remote packet capture, kernel-level packet filtering, and a network statistics engine. WinPcap has found its application in many open source and commercial network tools, including network monitors, network intrusion detection systems, protocol analyzers, traffic generators, sniffers, and network testers. The WinPCap project began in 1999 due to an emergent need to run tcpdump (a common packet analyzer that runs under the command line) on computers based on the Windows platform. The project was started by Gianluca Varenni, an Italian software programmer, and is currently being maintained by Riverbed Technology, Inc., an American company that develops WAN optimisation technology. Riverbed was founded in 2002 and is currently headquartered in San Francisco, CAlifornia, USA.
