Network Issue
-
Could also be a failing NIC, not just its driver. Long ago, failing NICs were the primary cause of this. Less likely to be a virus as there is little benefit to someone to make malware to just mess up your network a little.

@scottalanmiller What are the basic troubleshooting to be caried out for the issue to be resolved.How to identify the system without the Wireshark tools.Any other idea without the tools

The long way? Unplug ports from switches one by one to see which one is causing the issue. This is tedious and highly disruptive.
-
@coliver The production should not be disturbed for the client this is the situation

If you lack managed switches, this is the way to go. Short of standing in front of the switches and starring at them hoping to visually identify the traffic from the blinking lights.
-
@scottalanmiller Ok Thank you Sir

Without being able to use networking tools or look into the managed switch logs you probably won't be able to do this in a way that won't disrupt the production environment.

@coliver How to see the managed switch logs.Sorry,I am new to network related issue.Dont get angry guys.

Depends on the switch. Start by logging into it.

What brand and model are your switches?
-
@IRJ Digisol I didnot having model number but it was 48 port switch.The model is?

@scottalanmiller Sir can you please give any link to learn about the wireshark to get the null packets details in large network.Since I don't know about the software which is new to work to me.

Whether the system can be found out as a Virus affected through the switch log itself?or The system needs to be checked by any antivirus

You can find out which device or computer is causing the issues first. Once you get it narrowed down to that you can troubleshoot the device to see what is causing it.

Not if the packets are null. Right now you are just trying to find the machine in question.
-
@scottalanmiller Yes Just I need to find out the machine which is affecting the whole network

Yes, that's all you care about right now. Figure out what port is generating the traffic. Then unplug it and start to do diagnostics in a secure space.

Heck If it's really causing issues start upluging switch uplink ports and narrow it down to which switch the device is connected to. Then you can narrow your choices down much more.

@thecreativeone91 When I unplug the Uplink Cable means the network will be down for the users.It should not be happen for them know Sir.
