Real-Time ActiveX Control

Hello.
I am starting to develop a software that it needs to
have an interface in real-time with a object putting into motion
over a picture that represents a map.
This must be made through ActiveX Control to be used over the Web.

I started creating the control activex that shows objects in motion
on the map. But it is necessary that the ActiveX control receives the
data from positions X,Y from the Web server.

I creat an object COM that sends positions X,Y for the ActiveX control
on the browser, it works in my machine, however when I used in another
machine, the activex control arrives in browser but doesn't work.

A MesageBox appears with the advice
"Run-time error ' 429 ' ActiveX component can't create object".
The object COM already was created as ActiveX-EXE and ActiveX-DLL,
none of the versions functioned.

What it can be happening, I must use/set something for DCOM/MTS in my machine?

Somebody already saw or worked with this type of application
(ActiveX control receiving information from components COM in
real-time through the Internet)?

My server is IIS in the Windows 2000 Server.

Very obliged for the attention of all.
Edierley Messias.
