IIS set error HRESULT: 0x80090016 MachineKeys file empty

Question

User37103272 posted

I recently had to install a new hard drive (recovered backed up files) and reinstall Windows 10. I am trying to set up (again) an FTP site. [I had one up and running before the original drive failed.] I installed the IIS components (FTP server and IIS Management Console). I completed the Add FTP Site... dialog. When I try to update the authentication to a specified user I got "Keyset does not exist (Exception from HRESULT: 0x80090016)". My research led me to believe my MachineKeys file may not have the proper configuration information. When I looked in ...\system32\Microsoft\Crypto\RSA\MachineKeys, I found it is empty. I uninstalled and reinstalled IIS features with no change. Am I missing something from the Windows 10 install?

Hi Bleahuer,

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

First you can try to run the iisreset command(run as administrator) and check if it works.

If it still can't work, you can try to delete the existing keys inside the configProtectedData section in applicationhost.config and then running "%windir%\system32\inetsrv\iissetup.exe /install SharedLibraries".

Thanks, Sam. I've been down that path. The iisreset comman doesn't fix the problem. I cleared out the  <configProtectedData> content in ApplicationHost.config. When I run the iissetup utility I get the error "Failed = 0x80070005". I uninstalled IIS and reinstalled it with the same results - no MachineKeys for IIS.
