Continuous exceptions ‘Keyset does not exist’ (Exception from HRESULT: 0x80090016) or (Exception from HRESULT: 0x80090005) followed by (Value does not fall within the expected range 0x80070005)

Keyset does not exist (Exception from HRESULT: 0x80090016)

Basically, the machine key providers were corrupted because of which IIS was not able to decrypt the password set for Application pool. Due to this AppPool was throwing the above-mentioned error.


As a workaround we can follow the below article to fix the error by regenerating the machine keys:



But what should I do if I get the below error pop up which fails with “0x80070005” while regenerating the machine key providers using the command "iissetup.exe /install SharedLibraries"?

Value does not fall within the expected range.



Looks like the keys themselves were in corrupted state.



To fix this issue follow the below steps:

  1. Export the keys from a working server of same version using the below commands:

     aspnet_regiis.exe -pri -px "iisConfigurationKey" "c:\iisconfigkey.xml"
     aspnet_regiis.exe -pri -px "NetFrameworkConfigurationKey" "c:\netframework.xml"
     aspnet_regiis.exe -pri -px "iisWasKey" "c:\iiswas.xml"


  1. Run the commands in below folders:



  1. Once the keys were exported, move them to non-working server and import them using the below commands (we should run these in all the 4 folders mentioned above):

     aspnet_regiis.exe -pi "iisConfigurationKey" "c:\iisconfigkey.xml" -exp
     aspnet_regiis.exe -pi "NetFrameworkConfigurationKey" "c:\netframework.xml" -exp
     aspnet_regiis.exe -pi "iisWasKey" "c:\iiswas.xml" -exp 


  1. Now, regenerate the machine key providers once again using the command “exe /install SharedLibraries”.


Resolution Steps:

- Take the back up of machine key folder
- Run the above mentioned scripts
- Take the backup of applicationHost.config file and remove the <providers> section under <configProtectedData>
- Run the command "%windir%\system32\inetsrv\iissetup.exe /install SharedLibraries"
- Now, try to change the credentials for application pool identity
