Could not load file or assembly 'sapncp.dll' or one of his dependencies

Hi,

I have a web service made with WCF.NET 4.5. This web service would be used to obtain certain information from a SAP System using SAP.NET Connector 3.0.

The problem is: When I deploy the web service on a IIS 7 on W2K8 Server, i´m getting this error: "Could not load file or assembly 'sapncp.dll' or one of his dependencies". I´ve tried changing the configuration of the IIS but i can´t solve the problem.

Any clue?

Thanks in advance and best regards
