Microsoft Network Monitor logo

Microsoft Network Monitor (NetMon) is a software utility designed to help users capture network traffic and analyze incoming and outgoing packets. The packet analyzer is wrapped in a user-friendly interface and comes bundled with intuitive options.

A packet sniffer comes in handy for troubleshooting application connectivity issues. For example, you can detect the programs that use a surprisingly high amount of traffic, which is usually a tell of malware activity. Packet analyzers are also great for security analysis, whether you’re an expert or not.

Although Microsoft Network Monitor is discontinued and no longer receives updates, we still think it’s one of the best packet sniffers for your Windows PC. It works not only with older editions like Windows XP but also with modern iterations, including Windows 10.

Microsoft Network Monitor system requirements

Before you download NetMon to your Windows PC, check if your system meets these prerequisites:

  • Processor: 1 GHz or a more powerful CPU
  • Memory: at least 1 Gb of RAM
  • Free disk space: around 60 Mb for the program and more for saving files
  • OS: Windows 10, 8.1, 8, 7, Vista, XP, Server 2008, Server 2003

How to install Microsoft Network Monitor

There are two setup files available for download, x86, and x64, depending on your system’s architecture. Afterward, you can begin installing the Microsoft Network Monitor capture and parser engine before the parsers.

Besides reviewing and accepting the license terms, you can opt for using Microsoft Update to check for updates, as well as customize the setup package by excluding the program components, system path update, or documents. You can also place a shortcut on the desktop. It’s a good idea to restart your PC to finalize the setup.

Microsoft Network Monitor interface

When it comes to the graphical interface, it’s quite clear that Microsoft Network Monitor is outdated, judging by its Windows XP style. Nevertheless, it has a clear-cut main window that makes it easy to find all its options.

The layout is set to a simple mode by default, but you can change it to diagnostic or developer mode if you need to directly examine network data using the hexadecimal display. NetMon shows the network conversations and display filters, together with the frame summary and details.

How to use Microsoft Network Monitor

Here are simple steps to help you easily capture network traffic with NetMon:

  • Make sure to restart your computer after installing the packet sniffer
  • At program startup, select the network to analyze
  • Start a new network capturing session and begin network monitoring
  • The Network Conversations area gradually fills with network traffic
  • Select a process from the list to view its frame summary and details
  • You can load any filter to exclude unwanted network data
  • The displayed, selected or all captured frames can be saved to file

An excellent packet sniffer, even for Windows 10

Taking everything into account, Microsoft Network Monitor is an excellent software solution that can help you inspect network traffic, debug programs with Internet connection issues, detect possible malware activity, conduct security analysis, and more.

NetMon uses a decent amount of system resources while it scans the network adapter, so you shouldn’t expect any computer performance issues. It might be heavier on older PCs, though. The tool is wrapped in a user-friendly interface and comes bundled with many practical options for all types of users.

Even though it’s no longer supported, Microsoft Network Monitor is a great option for PCs. We haven’t experienced any compatibility issues when testing it on Windows 10.

Microsoft Network Monitor replacements

If you prefer a packet sniffer that still gets regular updates, then you might be interested in alternatives to Microsoft Network Monitor. Wireshark is a great choice and pretty popular when it comes to network protocol analyzers. It has a comprehensive set of features for deep inspection, along with offline analysis tools.

PRTG Network Monitor is another packet sniffer that deserves your attention. It’s a pro-level agentless security program that integrates advanced utilities for network monitoring and analysis. PRTG can tell you how your network bandwidth is being used by processes with the help of SNMP and NetFlow.
