I have a webservice that is calling a C# dll. This dll then calls methods in a VB COM+ component. The COM+ component instantiates ok; but, when I perform the first COM+ method call, a browser window materializes and the program seems to stop execution. The return value of the called function is an ADO recordset. Looking at the value of the variable in the watch window, it is undeclared. So, the function is not completing. I ran this code from a straight WinForms application and it worked fine. Is there something about webservices that would prevent me from doing what I am attempting? I got the following message in he output window:

Interop.Grading QueryInterface for interface Grading._clsGrading failed.

Thanks in advance for any assistance.
