Shibboleth SP 3.2.3.1 fails to run in Windows 2016 server + IIS 10

[Patrick Wong (ITSC)]

Dear Rod,

Thank you for your prompt reply. 

For "data" mentioned in Event log, I guess it refer to the  following  :

- <Event xmlns="http://schemas.microsoft.com/win/2004/08/events/event">
- <System>
  <Provider Name="Microsoft-Windows-IIS-W3SVC-WP" Guid="{670080D9-742A-4187-8D16-41143D1290BD}" EventSourceName="W3SVC-WP" />

  <Binary>05400080</Binary> 
  </EventData>
  </Event>

Following are my other update :

	- Verify that shibd is running and starts cleanly
	- Check the (shibboleth) EV entries and any other logging

-> It's a new installation and all logs are normal.

	- Check that there isn't some other extraneous configuration error in IIS (eyeball the applicationHost.config file)

-> Any suggestion  on how to "debug" potential issue in applicationHost.config file ?  What I can say is if I comment out the following lines in applicationHost.config the Application Pool won't down :

    <add name="ShibNative32" image="C:\opt\shibboleth-sp\lib\shibboleth\iis7_shib.dll" preCondition="bitness32" />
    <add name="ShibNative" image="C:\opt\shibboleth-sp\lib64\shibboleth\iis7_shib.dll" preCondition="bitness64" />


	- Leaving the install in place disable and reenable the IIS7 module

->  It doesn't help.

Best Regards,
Patrick

What does the data say ?

Some random thoughts:

	- Verify that shibd is running and starts cleanly
	- Check the (shibboleth) EV entries and any other logging
	- Check that there isn't some other extraneous configuration error in IIS (eyeball the applicationHost.config file)
	- Leaving the install in place disable and reenable the IIS7 module

My go to tool in these cases is always procrun, but that is because of my background so I am leery of recommending it to others.
