Network Monitor Beta

The networks monitoring team announcement the new beta of netmon. I use this tool frequently when troubleshooting dcrefresh issues and streaming problems that customers have. So when I saw the new beta, Just had to let you all know. Plus using the PID you can really identify the useful traffic!!!


Network Monitor 3.2 Beta is available!

We are our proud and excited to announce the release of NM3.2 Beta, available at Please visit the Network Monitor Project on Microsoft Connect and download the Network Monitor 3.2 Beta. You can also view the FAQ from the home page for more information about the latest version.

Also remember that you can visit our blog for continued updates about using NM3 and network troubleshooting in general:

What's New since Network Monitor 3.1

  • Process Tracking: View all the processes on your machine generating network traffic (process name and PID). Use the conversation tree to view frames associated with each process.

  • Find conversations: Quickly isolate frames in the same network conversation. Isolate TCP streams, HTTP flows etc.

  • PCAP capture file support*
  • Capture engine re-architecture to improve capture rate in high-speed networks. NM 3.2 drops significantly fewer frames that NM 3.1

· Extensive parser set: Parsers for over 300 protocols! Parsers for the protocols covered by the Windows Open Protocol Specifications (see

· NM API: Create your own applications that capture, parser and analyze network traffic!

  • Better parser management: By default only a subset of parsers are loaded. You can load the full parser set by changing the parser search order in Tools>Options>Parser
  • Support for frame truncation. Go to Tools>Options and limit the number of bytes captured per frame to improve performance.
  • More extensive documentation of the NPL which includes documentation on the new NMAPI. Access the documentation from Help > NPL and API Documentation
  • Enhanced filtering on items within NPL while loops or arrays. You can specify an index into the array or while loop to filter on
  • IA64 version now available.
  • ContainsBin Plug-in: Search frames for arbitrary byte sequences or strings. For example, ContainsBin(FrameData, ASCII, "msn").
  • More UI indications of conversation status, dropped frames and the number of frames in the capture buffer.

  • . and more. See our Release Notes in the NM3.2 installation directory for a complete list of new features and known issues with the Beta.
