I run Debug Diagnostic tool on my windows server 2008. It created dump files.
Because my asp.net application gives an exception time to time.

I need step by step instruction how to debug dump file. Do I need to debug in production server or locally? What do I need to have? How to configure?

How to determine where in application is the problem?

Is there any other ways how to read Dump files? 

Here is the post I found it has pretty good explanation about dump files but they didn't explain the debugging part
