finally I got the script running.

for that executed the commands regasm path/mydll.dll

                                               regasm path/mydll.dll/tlb

                                               gacutil mydll.dll

and when executed the web application I got the alert.

<script type="text/javascript" language="javascript">
   <!-- Load the ActiveX object  -->
    var x = new ActiveXObject("DimensionsClientsSystemInfo.DimensionsClientsSystemInfo"); 

    alert(x.MacID());

    var XLApp = new ActiveXObject("Word.Application");
     
   alert(XLApp.Version);
    
  </script>

all works fine but when I published the web application and executed it from the server,the same error repeats

"Automation server can' create object"

should I alter any another settings???

pls help.....
