Hi friends !
Some days before, Our network went down. Not completely but partially. All the users complained that there is extremely slow internet performace. After a long effort, we came to know that there was a computer which was infected with harmful threats and it was sending broadcasts again and again. When we removed that computer from the network, sometimes after the network was ok.
Now, I want to know how can I monitor all the network activities from a centralized location ? I have heard about network monitor tools. Do you have any idea about some free network tools to test in evaluation period ? What is the way to monitor the network ? How can I know which computer is responsible for degrading network performance ?
