Com + ....what Port Does It Use?

Hello,
I hope someone could help me out here....

I have set up a new web server in my DMZ. This web server needs to "talk" to an application server located on my LAN. It communicates via a COM + Component.

I would like to keep the access that is open between the DMZ & LAN to minimal, obviously for security reasons. Does anyone know what port is used for COM + communication?

Thank you!

SpootnicksThis is the site that I always use to answer port questions:
http://www.iana.org/assignments/port-numbers

Having said that, I don't immediately see the answer. I think it's because COM+ isn't what you're looking for. I think it MS's port for remote procedure call or something.

Sorry for the vague answer. I hope the web page helps at least.

Regards,
