Does the Window server show port 5666 up and listening if you run "netstat -na" ? It could be that the nsclient service isn't running or that it's configured to listen on a different port. Check the nsclient.ini(or nsc.ini) file as well to make sure that the XI machine's IP address is in the "allowed hosts" list - https://docs.nsclient.org/reference/win ... owed-hosts
