This error may occur due to the Firebird architecture specificities, not due to IBDAC functionality. When working with event, client and server try to establish an additional connection using random ports. These ports may be blocked by the firewall (antivirus), and you will get the described error as a result. To solve the issue, you can disable your firewall (antivirus) or set a specific value in RemoteAuxPort in the firebird.conf file, and setup the firewall (antivirus) so, that it doesn't block the specified port.
