Nagios Support Forum

Hello,
i'm testing nagios core 4.4.5 ncpa 2.2.0 on a windows windows 2003 service pack 2 server.
The check are all active and default but I get this message for every service.
UNKNOWN: An error occured connecting to API. (Connection error: '[Errno 111] Connection refused')
How can I troubleshoot that?
Thank you in advance.

I think the only time you should get a "connection refused" message is if the service just isn't there. Is there any indication that NCPA is crashing and restarting?

you are right.
on windows 2003 servers I can't find the NCPA listener and the NCPA passive services in services.msc
The steps performed were: install on the win2003 server ncpa 2.2.0
during install i got no errors.
But at the end those services are missing.
Using version NCPA 1.8.1 works.

1.8.1 appears to be the only version that will support 2003:
