Hello,

Normally "Connection Refused" is caused by firewalls actively closing the requests. Also, please note that by default named instances use dynamic ports and do not listen on 1433. If you are using dynamic ports, make sure the browser service is started and that UDP 1434 is allowed for browser service communication.
