You will then see the following messages for several minutes (how long will depend upon a number of factors including server specification, performance, trace file size etc): Correlating traces. To stop the trace, enter the following syntax : netsh trace stop Once you have replicated the problem you are troubleshooting, you will need to stop the trace.

This reduces the amount of packets capture which reduces space usage and aids in easier troubleshooting by filtering out traffic that is not of interest The IP address of the server communicating with this server whose traffic you wish to capture.

This may be enforced by AppLocker or other controls. If you need to capture network traffic from a Windows server, you may find that that standards or controls in your organisation prevent or forbid you from installing tools such as Wireshark on your Windows servers.
