You can disable notifications by either Acknowledging a host problem, or by accessing the host details, and there's a link to "Disable Notifications." We had an major bug in the release 2011R1.4 that created this kind of issue. If you're using 1.4 we recommend upgrading to 1.5 immediately to correct the problem.

Renuka,

Connection refused usually means a firewall is blocking or the nsc.ini isn't configured properly. Are you aware of a firewall change on that particular host?

Does the nsclient.log show anything (its in the same directory that NSClient++ is installed in.)? Did the Windows firewall get activated? Do the ports that your checking from the Nagios XI box and the port open on the firewall and the port in the nsc.ini match?

To stop alerts from that particular host it would be probably be quickest to disable Alerts. I'm not sure which command you issued, but try this:

Home (Top Tab) > Host Details (Left Side Tab) > Host you want to change > Disable Notifcations
