We have built a C++ COM component that is talking to an application engine. ASP is calling the COM component and asking the application engine to perform a specific function and return results. We have no problems with single attempts through ASP to COM to the engine and back. When two simultaneous attempts occur, the Web Server bombs (the engine stays running). We know the Engine is multi-threaded and belive in testing that the COM object is multi-threaded, so what is the issue. I am creating and destroying the object on a single page. Nothing is hed in Session... does anyone have any ideas as to what to look for, is it the way the COM component is built or an ASP/IIS thing??<BR><BR>Thanks in advance,<BR>Jeremy<BR><BR>
