I wrote a post about how I captured a NETSH trace here "Capture a NETSH network trace". I like to use Wireshark to analyze my network traces, this post describes how I analyzed a NETSH .ETL trace file in Wireshark.
NOTE: Wireshark is not a Microsoft product it is a 3rd party tool.
Here is a link to the archived version of Network Monitor 3.4.
First, after installing Microsoft Message Analyzer, open it and select File –> Open –> From File Explorer, as see in Figure 1.

Once exported, open the .CAP file in Wireshark or Network Monitor. See my other post here that explains some about how I analyzed the trace.
