SSIS: Active X Script task to call Webservice

I am facing an issue while executing the SSIs package in SQL server 2008. I have used an ActiveXScript Task within it to call a webservice method in order to return a set of records in XML format.

I have called th eas Set xmlHTTP = CreateObject("Microsoft.XMHTTP");

I am getting the below error sometimes and sometimes it run successfull.

msxml3.dll error The download of the specified resource has failed.

Does anyone have any suggestion why this is happening?

I am using VB language within it.

Thanks in advance.
