|what is DOS command to list all servers related to network|
To the best of my knowledge, there is no such command.
Yet there are many different network and local servers and services listed as active in task mgr
I'm not sure what you mean by the above statement. I think instead of ""local servers and services" you must mean just "services" alone. Typically, a "server" is a computer that provides "services" such as DHCP, NAT, email etc. Or, are you referring to the list of processes running on the "processes" tab of Task Manager?
If you're talking about the "processes" tab in Task Manager then those are just services and applications running on your local computer. Most you want to just leave alone as they are necessary for proper running of your computer.
You can google each and every one of them to see where it comes from and what it does if you're concerned about them.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
