debugging a crash (c++)

I am having a service which calls a C++ COM dll. The C++ COM dll causes some pr开发者_运维知识库oblem and the service crashes.

I couldn't figure it at what point the service crash. I used debugdiag. But it is not putting any crash dump.

Kindly let me know how I can debug a application crash. Or direct me to some good tutorials and tools.

Many thanks.

Attach the Visual Studio debugger to your service via Tools / Attach to process. You might need to check Show processes from all users in order to see your service in the list.
