Hello Neil: 

Thank you for posting here in the DNN Community forums! 

Unfortunately, there isn't much information for any of us to use to help you, yet.  They're just snippets of details.  What steps did you take to perform the installation, specifically?  All details matter.  

Just in case it helps, I created this playlist on YouTube a while back.  The first two videos, specifically, are great primers for the step you're currently in.

Found fix was to install more features for IIS:
Under Security sub-section choose everything (I excluded digest, IP restrictions and URL authorization as we don't use them)
Under Application Development choose .NET Extensibility 4.5, ASP.NET 4.5 and both ISAPI entries
In the features section choose: NET 3.5, .NET 4.5, ASP.NET 4.5

Awesome news!  Thank you for letting us know.  :) 

 

I had the same issue when moving to Windows 2022. This has been a setting that is really old, but never got into effect for some reason. Anyway, I found it in Windows 2012 R2 already, and maybe it is even older...

After (a lot of) investigation, I found out that there is a file called applicationHost(dot)config (in C:\Windows\System32\inetsrv\config), and there you find some entries like

<section name="anonymousAuthentication" overrideModeDefault="Deny" />
<section name="basicAuthentication" overrideModeDefault="Deny" />
<section name="windowsAuthentication" overrideModeDefault="Deny" />

That means that for these settings it is denied to override in the web(dot)config file, resulting in a 500.19 error. You have two possibilities:

• Either you change "Deny" to "Allow" in this file, or
• you delete this section from the web(dot)config file (remembering the setting!) and set it back in the IIS Management Console.

If you choose the second option, you will find entries like

<location path="Default Web Site">
 <system.webServer>
  <security>
   <authentication>
    <anonymousAuthentication userName="" />
   </authentication>
  </security>
 </system.webServer>
</location>

in the file applicationHost(dot)config.

Happy DNNing!

Excellent advice, Michael! :)
