Microsoft Network Monitor is a deprecated packet analyzer. It enables capturing, viewing, and analyzing network data and deciphering network protocols. It can be used to troubleshoot network problems and applications on the network. Microsoft Network Monitor 1.0 (codenamed Bloodhound) was originally designed and developed by Raymond Patch, a transport protocol and network adapter device driver engineer on the Microsoft LAN Manager development team.

The LAN Manager development team had one shared hardware-based analyzer at the time. Netmon was conceived when the hardware analyzer was taken during a test to reproduce a networking bug, and the first Windows prototype was coded over the Christmas holiday. The first 4 bytes of the Netmon capture file format were used to validate the file. The values were 'RTSS' for Ray, Tom, Steve, and Steve - the first four members of the team. The code was originally written for OS/2 and had no user interface; a symbol was placed in the device driver where the packet buffers were kept so received data could be dumped in hex from within the kernel debugger.
Netmon caused a bit of a stir for Microsoft IT since networks and e-mail were not encrypted at the time. Only a few software engineers had access to hardware analyzers due to their cost, but with Netmon many engineers around the company had access to network traffic for free. At the request of Microsoft IT, two simple identification features were added - a non-cryptographic password and an identification protocol named the Bloodhound-Oriented Network Entity (BONE) (created and named by Raymond Patch as a play on the codename Bloodhound).
Network Monitor is the archived protocol analyzer and is no longer under development. Also, Microsoft Message Analyzer (MMA) was retired and its download packages were removed from microsoft.com sites on November 25, 2019. There is currently no Microsoft replacement for Microsoft Message Analyzer in development at this time. For similar functionality, consider using another, non-Microsoft network protocol analyzer tool. For more information, see Microsoft Message Analyzer Operating Guide.
To get started, download Network Monitor tool. When you install Network Monitor, it installs its driver and hooks it to all the network adapters installed on the device. You can see the same on the adapter properties, as shown in the following image:
The saved file has captured all the traffic that is flowing to and from the selected network adapters on the local computer. However, your interest is only to look into the traffic/packets that are related to the specific connectivity problem you're facing. So you'll need to filter the network capture to see only the related traffic.
You can see the protocol and description of each frame. We have a lot of traffic on RPC and SMB and from the frame description we see that this is communication on named pipes: Netlogon, Samr, and LSARPC. These are the connection points involved in a domain join between a workstation and a domain controller. By highlighting one of these frames in the Frame Summary pane, we can see each network layer of the frame in the Frame Details pane.
If we look at either the network trace taken on the domain controller or the trace taken on the workstation, there will be a frame with an Identification number of 3201. You can filter both traces for this frame by using the filter IPv4.Identification == 3201 .
We see that the last packet sequence number sent in this frame is 4167329214 , and the last packet that we received from our partner in this communication is 1946363494 . These numbers can often be misleading, because a router can strip and resend at the network layer (IP layer) and all the numbering can be misleading from the IP layer up (In this case TCP.) To align to simultaneous traces, I use the Identification attribute from above, and I use the sequence and acknowledgement numbers to verify dropped and received packets.

Even though this blog is AskDS, it is important to understand the networking components used by Directory Services. By using Network Monitor, you can avoid time spent troubleshooting the wrong component.
So I run the network monitor, on select networks I have selected Wireless Network Connection (I connect to internet using wifi), but when I start a new capture, internet stops working. And if I click the wifi tray icon instead of "Connected" it says "Limited access", when I stop the capture it changes back and internet starts working again.
Monitor and diagnose networking issues without logging in to your virtual machines (VMs) using Network Watcher. Trigger packet capture by setting alerts, and gain access to real-time performance information at the packet level. When you see an issue, you can investigate in detail for better diagnoses.
Build a deeper understanding of your network traffic pattern using Network Security Group flow logs. Information provided by flow logs helps you gather data for compliance, auditing and monitoring your network security profile.
An exclusive feature of the Microsoft Network Monitor is that it can decode various protocols. This makes it easier to find out what types of traffic or malicious activities are in the network.
A study done by TechRadar showed that people who used the Microsoft Network Monitor cut their troubleshooting time by 30%. This shows how effective and reliable this tool is when it comes to streamlining network analysis.
Microsoft Network Monitor is here to help you effortlessly analyze and troubleshoot network traffic. With this powerful tool, you can gain deep insights and identify issues in real-time. You can capture and examine network packets to monitor and analyze communication between devices on your network. This simplifies the task of network monitoring, even for those just starting out.
Its reliability and effectiveness have made Microsoft Network Monitor a staple in the world of networking. Countless organizations have used this robust software to diagnose intricate network issues and optimize their systems. Its success is a true testament to its power.
In conclusion, effective analysis needs a methodical approach of packet inspection, protocol examination, conversation evaluation, and filtering. This process enriches network troubleshooting, performance tuning, and security in the network infrastructure. Microsoft Network Monitor helps reach the full potential of network analysis.
Microsoft Network Monitor is a powerful software with various features and tools to monitor and analyze network traffic. Capture filters allow users to select the type of traffic they want to monitor. Packet analysis digs deeper into the details of individual packets and their contents. The expert system provides knowledge about networking protocols and their behavior patterns. It even helped to uncover a security vulnerability that affected a widely used networking protocol. Utilizing this tool helps professionals efficiently monitor and analyze networks. It supports optimal performance and security for organizations that rely on reliable network communication.
Microsoft Network Monitor is a great help for network admins. Its user-friendly interface and analysis abilities have made it a valuable asset. It offers a lot of filters and options for deep packet analysis. This helps admins to rapidly detect and fix problems, keeping the network running smoothly.
Also, real-time monitoring and packet capture on multiple interfaces is available. This keeps users informed about any potential issues or security threats. Plus, Microsoft Network Monitor is integrated with other Microsoft products, such as Wireshark, to aid more comprehensive networking analysis.
Ever wondered what is flowing over your network? Is some compromised machine distributing spam? Are emails being sent over an authenticated connection? Are login credentials being transmitted unencrypted? These are some questions a network sniffer can help answering, opening a window on the network lifeblood.
Network Monitor is made up of a driver that captures traffic reaching the local Network Interface Cards NIC and a UI that allows us to analyze the collected data. Even though the monitor interface does a good job in organizing and filtering captured data at the end we are still looking at raw network traffic. Thus a basic understanding of the transport protocol namely TCP and UDP certainly helps.
Avoiding excessive technicalities, the Monitor presents snippets of data packaged into frames. Each frame includes enough information to identify the protocol, the source and destination hosts amongst others. Depending on the application the frame will also carry data specific to that application protocol. As we shall see the monitor also packages a number of protocol specific parsers. These allow it to provide a richer view for frames from standard protocols.
Anyone new to Network Monitor and similar sniffing tools are likely to be initially overwhelmed by the amount of data presented to them. Installing the monitor on an Exchange server, we are likely to see OWA HTTP/SSL traffic, DNS queries, SMTP traffic, and a lot more. There is just too much going on. Indeed these tools are most useful when searching for something specific. For example we could be looking for SMTP email reaching the server from some specific IP.
Follow this link to download Network Monitor v3.2 and proceed with the installation. The initial Monitor interface presents three panes. At the bottom left we can choose the network interfaces from which data is to be captured.
If you run Network Monitor on a machine where you can tightly control what is running, you will be able to determine exactly when a process shows up in the left pane. For example here I submitted a DNS query using nslookup.exe and immediately dns.exe showed up at the monitor. Likewise using telnet I submitted one email to the test Exchange server and edgetransport.exe was added. This method enables us to identify processes that are listening to a specific port.
