Unhandled error soap:server unble to progress request file or assembly name some.dll, or one of its dependencies, was not found

Hi,

I am developing web application with OWC10 and Web serice and OLAP AS. I had developed the reports and working in my local pc fine. but when I installed in the server I am getting below error as a popup.

Unhandled error soap:server unble to progress request file or assembly name <some>.dll, or one of its dependencies, was not found

dll name is always changing.

I developed using microsoft samples as like this http://msdn.microsoft.com/msdnmag/issues/03/10/OLAP/

I had done all the grantings and necessary configuration aslo.

Please advice what could be the reason.. it's very urgent.

Thanks
