macromedia flash flashcom: Hello!

I have a problem. I installed FMS2, and downloaded sample apps from the
devcenter. I'm running Microsoft IIS and I can access http://myip/fms and go to
any applications, the work just fine, I can see video.

Now I try to use another computer on the network, I access the same URL, I see
html, I click on application link, I see flash, but it doesn't connect to the
server. The little black light on the flash application never turns green, and
I don't see anything in the FMS logs on the server.

What am I doing wrong?

Thanks!!!
