Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Packet Monitor Pktmon is an in-box, cross-component network diagnostics tool for Windows. It can be used for packet capture, packet drop detection, packet filtering and counting. It is available in-box via the pktmon. Any machine that communicates over the network has at least one network adapter.
All the components between this adapter and an application form a networking stack: a set of networking components that process and move networking traffic. In traditional scenarios, the networking stack is small, and all the packet routing and switching happens in external devices. However, with the advent of network virtualization, the size of the networking stack has multiplied. This extended networking stack now includes components like the Virtual Switch that handle packet processing and switching.
Such a flexible environment allows for much better resource utilization and security isolation, but it also leaves more room for configuration mistakes that can be hard to diagnose. Packet Monitor provides the enhanced visibility within the networking stack that is often needed to pinpoint these mistakes. Packet Monitor intercepts packets at multiple locations throughout the networking stack, exposing the packet route. If a packet was dropped by a supported component in the networking stack, Packet Monitor will report that packet drop.
This allows users to differentiate between a component that is the intended destination for a packet and a component that is interfering with a packet. These drop reasons provide the root cause of the issue without the need to exhaust all the possibilities. Packet Monitor also provides packet counters for each intercept point, enabling a high-level packet flow examination without the need for time-consuming log analysis.
Packet Monitor is available in-box via pktmon. You can use this topic to learn how to understand pktmon syntax, commands, formatting, and output. The extension helps you diagnose your network by capturing and displaying network traffic through the networking stack in a log that is easy to follow and manipulate.
You can use this topic to learn how to operate the tool and understand its output. The tool automates Packet Monitor-based packet captures according to various SDN scenarios, and presents the output in a single view that is easy to follow and manipulate. Packet Monitor generates logs in ETL format. These logs can be analyzed using Microsoft Network Monitor Netmon by using special parsers. Packet Monitor can convert logs to pcapng format.
Starting with Windows 10, version and newer based device or computer, you can't uninstall the Client for Microsoft Networks or other network components. You receive the following error message:. Microsoft doesn't support using this GUI or netcfg to uninstall protocols or built-in drivers. This is effectively the same as uninstalling the driver. If there are specific drivers that you want to remove but that are currently not part of an optional feature, file a feature request in the Feedback Hub.
