A search in the Microsoft Knowledge Base for COM+ ports to open for firewalls[^] yields what you want. The first result - How to configure RTP dynamic port allocation to work with firewalls[^] is probably what you want. The linked article How to configure a firewall for domains and trusts[^] might also be helpful to solve potential authentication issues. You could also define either a specific unused port for the COM+ component or a static range for all components and open those on the firewall, but the former would be more secure. Don't forget to open ports on the client Also keep in mind authentication. Once you've solves connection problems make sure that you've set up the appropriate authentication and authorization for your component using the Component Services MMC snap-in. Much of that can be configured using the appropriate attributes on your COM+ service, too. This posting is provided "AS IS" with no warranties, and confers no rights.
