What Is The Difference Between The Network Monitor Agent And Network Monitor Tools And Agent? If you are using Network Monitor Agent on a remote computer, the local workstation does not need a network adapter card that supports promiscuous mode, but the remote computer does. To use Network Monitor, your computer must have a network card that supports promiscuous mode. This mode enables Network Monitor to capture and display all network traffic. Promiscuous mode is a state in which a network adapter card copies all the frames that pass over the network to a local buffer, regardless of the destination address. What If The Network Adapter Card Does Not Support Promiscuous Mode? What Is Promiscuous Mode Anyway?

The full version of Network Monitor also allows you to capture and display any frames from the network segment on which the computer that is running NetMon resides, regardless of whether they are addressed to the host computer. Both versions of Network Monitor can capture traffic that is sent to or from the host computer (the computer that is running NetMon), including broadcasts and traffic over a dial-up network connection. It depends on what kind of traffic you need to capture. Yes, the overhead of NetMon is minimal, and other applications should not be impacted by Network Monitor.
Can The User Run Other Applications While Network Monitor Is Capturing Or Filtering The Network Traffic?

A “lite” version is included with Windows NT Server and Windows 2000 Server and contains a subset of the features that are available in the full version. The full version is shipped with Microsoft Systems Management Server (SMS). There are two versions of Network Monitor. To do this, click Load on the Capture Filter or Display Filter dialog box. These files are usually located in the WinNT/System32/Netmon/Captures/ folder.Īlternatively, you can save and load various filter files as needed from within Network Monitor. The default Display filter file is named Default.df, and the default Capture filter file is named Default.cf. To save a Capture or Display filter as the default, you must write over the existing file. Can Capture And Display Filters Be Saved As The Default? If you have three computers that communicate in a three-tier architecture, you can run Network Monitor on the middle tier because all traffic crosses that computer. In this scenario, you can compare traces more efficiently if you use the Net Time command to synchronize the system time on the computers. You may need to trace on both the client and server if a firewall or intranet is causing network problems. When you are troubleshooting HTTP or other text-based protocols, if you have two computers, and the client is getting back unexpected results, run Network Monitor on the server to see if the server is sending the correct data. Thus, you cannot use Network Monitor to understand what is happening between the applications. Usually, when client and server applications are on the same computer, there is no network traffic. Should I Run Network Monitor On The Client, The Server, Or Both? What If The Client And Server Are The Same Computer?
