Trouble with ActiveX, pls help me

Hi friends! I have a trouble with using ActiveX control in VB.NET:

I created an OCX in VB6 and I successfully embedded it in my ASP.NET application. It works well when I run my ASP.NET app in the my own computer (using IE to open the webpage created by the app, through http://localhost/mywebpage), but it does not when I try to run the app from another computer (using the same way to open). The webpage is opened, but the OCX control is not loaded (an empty place is there in the place of the OCX).

I dont know why and it is hard for me because I am a newbie in this field. Someone who knows please clear this error for me? This is very urgent coz I have to submit it within 2 days.
Thank u very much.
