As we shall see the monitor also packages a number of protocol specific parsers.
Depending on the application the frame will also carry data specific to that application protocol. Each frame includes enough information to identify the protocol, the source and destination hosts amongst others. Thus a basic understanding of the transport protocol namely TCP and UDP certainly helps.Īvoiding excessive technicalities, the Monitor presents snippets of data packaged into frames. 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.

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. So you may want to double check for a newer release. At the time of writing version 3.3 Beta was being finalized as announced in the Network Monitor blog. Version 3.2 now supports Windows Server 2008, 2003, Vista and XP. The latest release is downloadable from the Microsoft Download Center. This could be installed directly from the Add/Remove Programs applet. The first Network Monitor releases were included with Windows 20. In this article I will be using the Microsoft Network Monitor version 3.2. 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.
