Microsoft network monitor gtalk

There are two versions of Network Monitor. A "lite" version is included with Windows NT Server and Windows Server and contains a subset of the features that are available in the full version. Which version should I use? It depends on what kind of traffic you need to capture. 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.

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. The Network Monitor Agent monitors the network and passes traffic up to the "program" the user interface. The Network Monitor Agent can run on any compatible computer while the program is running on a separate computer.

A computer can only see network traffic that passes across its network segment. Thus, it can be helpful to have a Network Monitor Agent that is running on a network where the problem is occurring, while the Network Monitor user interface runs from for example the local area network LAN Administrator's computer on a different network segment. The LAN Administrator can then manage the capture and view the captured data from his or her computer, even though the LAN Administrator is not on the segment where the problem is occurring.

What security risks are introduced by the use of Network Monitor? Network Monitor is a "sniffer," namely, it detects problems on the network. Because you can analyze traffic at the frame level, all non-encrypted data is visible in a trace. What is the difference between a media access control address and an IP address?

How can I distinguish one from another? A media access control MAC address is a unique, digit bit , hexadecimal number that the network interface card NIC manufacturer "burns into" a computer's network interface card.

On some cards, software can override this number, but the number remains burned into the card. The media access control is the lowest layer of the network model that contains address information. All frames on a local area network contain a MAC address, regardless of the network protocol in the frame. The same cannot be said about Internet Protocol IP addresses, which reside at a higher level of the network model.

IP addresses are usually represented in dotted-decimal notation, which depicts each octet eight bits of an IP address as its decimal value and separates each octet with a period for example, When you view captured data in Network Monitor, you can set up a friendly name for either type of address.

To do this, right-click the address in the Summary pane of the Frame Viewer window, and then click Edit Address. What if the network adapter card does not support promiscuous mode? When you suspect that the issue is on the network, you collect a network trace. The network trace would then be filtered. During troubleshooting connectivity errors, you might come across TCP reset in a network capture that could indicate a network issue.

TCP is defined as connection-oriented and reliable protocol. One of the ways in which TCP ensures reliability is through the handshake process. Establishing a TCP session would begin with a three-way handshake, followed by data transfer, and then a four-way closure. The four-way closure where both sender and receiver agree on closing the session is termed as graceful closure.

TCP reset is an abrupt closure of the session; it causes the resources allocated to the connection to be immediately released and all other information about the connection is erased.

A network trace on the source and the destination helps you to determine the flow of the traffic and see at what point the failure is observed.

When one TCP peer is sending out TCP packets for which there is no response received from the other end, the TCP peer would end up retransmitting the data and when there is no response received, it would end the session by sending an ACK RESET this means that the application acknowledges whatever data is exchanged so far, but because of packet drop, the connection is closed. The simultaneous network traces on source and destination will help you verify this behavior where on the source side you would see the packets being retransmitted and on the destination none of these packets are seen.

This would mean, the network device between the source and destination is dropping the packets. Approximate size Age rating For all ages. Category Productivity.
