Zabbix problem : Connection refused

For Connection refused , check if your windows server has zabbix agent running and pointing to the server you desire ( check server= variable in zabbix_agentd.conf), also check if you have firewall up , allow zabbix ports in your windows firewall.
Also you can login to zabbix server, check in command line via

zabbix_get -s WINDOWS_SERVER_IP -i agent.ping

Thanks
