Packet capture via cmd
Solution 1:
Windows 7 and above have this feature built in. http://blogs.msdn.com/b/canberrapfe/archive/2012/03/31/capture-a-network-trace-without-installing-anything-works-for-shutdown-and-restart-too.aspx
The short version:
Open an elevated command prompt and run:
netsh trace start persistent=yes capture=yes tracefile=c:\temp\nettrace-boot.etl
(make sure you have a \temp directory or choose another location).Reproduce the issue or do a reboot if you are tracing a slow boot scenario.
Open an elevated command prompt and run:
netsh trace stop
Your trace will be stored in c:\temp\nettrace-boot.etl** or where ever you saved it. You can view the trace on another machine using netmon.
