I am very happy about the help here. It works now.
But can you put al this wisdom in the official “Check manual page of win_netstat” : it contains now not much usefull information about it (exept the fact that the agent needs to be installed).
A feature that exists for more than 5 years and is “official part of Check_MK” , i would expect a decent “Check manual page of win_netstat”.
