Note: Make sure the dump is not generated by an application pool recycle by checking the event log.
*Debug Diagnostic 2.0 can be download at the following URL: https://www.microsoft.com/en-us/download/details.aspx?id=49924
If the operating system is 32-bit, install the 32 bit DebugDiagx86.msi. For 64 bit operating system choose the DebugDiagx64.msi.

*In the window "Select Target Type" 
**Check "A specific IIS web application pool", then click on "Next >"
This will have for effect to only generate a dump on the W3WP.exe process corresponding to your Application Pool 
*If you want to monitor every processes owned by IIS, you can select "All IIS/COM+ related processes"
*You can also select "A specific process" to monitor every instances of a process or just a unique one (a specific process with a specific PID)
The drawback of "A specific process" for a unique instance is you need to recreate the rule each time the process is restarted as his PID would have changed

*Select the Application Pool facing the crash issue, then click on "Next >" For your site, it should be AgilityNET2

*Add the breakpoint as you can see in the below screenshot 
**This allows you to generate a dump as soon as the command "TerminateProcess" is sent in the process without waiting for a complete stop
**In addition, if a problem is detected by WAS in the process, it will stop it with this command, so without this breakpoint, no dump will be generated while the process is facing a crash

*Check the status is "Active" 
**If it's not, The "DbgSvc" service is surely not started
**You can go in "Administrative Tools > Services" and start it
*When a dump will be generated, you'll see the column "UserDump Count" being incremented
The dumps are located by default in "C:\Program Files\DebugDiag\Logs\Crash rule for all IIS_COM+ related processes" or in "C:\Program Files\DebugDiag\Logs\Rule_Name".

If you see the following dialog box, choose No because we only need to generate dump files.
