Capturing memory dumps for 32-bit processes on an x64 machine

This is an issue that I often get questions around and we often have cases where we have to re-capture memory dumps because the memory dumps were captured the “wrong” way. The short story is: If you are executing a 32-bit process on a 64-bit machine, (which is the default case for IIS on x64…

Getting full user mode dumps automatically when your process crashes

I recently got a question about if it is possible to generate full user mode dumps automatically every time the process crashes (without having debug diag or adplus installed and monitoring your system).   This would be useful for example if you are setting up a site, and you want to make sure you get dumps…
