If there is a service or executable related to the DLL, you can use performance monitor and trace all counter on that process.

So what I need to do is prove it. I think I know which dll it is but I want to be able to track the server performance when the DLL is called. I can see via Dependancy walker that it is being used, but as to the frequency and its correlation to tthe given problem I don't know of a tool that can accomplish this task. Does anyone else out there know. What I would also like to know is how Microsoft prove that a particular DLL is causing a problem.
