The nature of Network Monitor 3.3

' A tool used for observing network packets sent and received over a network connection or from a previously captured data file. In addition, the tool provides complex network data filtering options . '
In other words, Network Monitor is a protocol analyzer (protocol analyzer) or 'packet sniffer'.

Overall, it will give you insight into your network unlike other solutions!
3. What is the cost of Network Monitor?
Unlike many other protocol analyzers (costing hundreds of thousands of dollars), Microsoft's Network Monitor product is completely free.

What is Experts and how do you use them?
The Experts feature of netmon 3.3 is an important feature. We have seen this feature before in thousands of dollars of data analyzers, so it is fortunate for us to get this feature from Microsoft's free data analyzer. Basically, Experts acts as a deep-rooted network administrator who can analyze the data and as assistants in speeding up data for you.
In other words, Experts will save you considerable time and give you answers to tough problems.
There are no Experts in netmon 3.3 that you need to download these tools from the Internet (completely free). To use experts, you must save the captured files, then reopen them. Note Experts will not work on 'live' data.
You can download Experts here.
Once you've done the capture, close, and reopen files, you can access Experts. You can access experts in two ways:
- Right-click on a frame and go to the Expert menu .
- Go to Experts menu from the drop-down menu.
