Is is possible to install ArcGIS Web Adaptor without Windows Authentication? I am installing ArcGIS Web Adaptor for Server and Portal. I need to enable ISS components and I realized that I do not have Windows Authentication. I am using Windows 10 Home edition. How should I go about installing Web Adaptor as the installer will not let me proceed without enabling all the ISS components requirements.
Windows 10 Home edition doesn't include Windows Authentication (and a bunch of other IIS security features). However, the package with these features is sitting right there in your OS and you can manually install it.
All you need to do is open an elevated command prompt and run:
dism /online /norestart /add-package:%SystemRoot%\servicing\Packages\Microsoft-Windows-IIS-WebServer-AddOn-2-Package~31bf3856ad364e35~amd64~~10.0.16299.15.mum
Filename above may be slightly different since it's based on your system's bitness and version
Then just make your way back to:
Turn Windows features on or off > Internet Information Services > World Wide Web Services > Security
All the "pro" options under Security will be available. Simply check "Windows Authentication" and reboot.
No. ArcGIS Web Adaptor requires some IIS components. Look at the documentation Enabling IIS and required IIS components
As ylka points out, IIS is not necessary per se, but in order to run ArcGIS Server you, uh, need a server. Now I suppose that you could try and use any old server stack you like and try to hack ArcGIS into it, but I suspect that this isn't exactly your speed. ylka proffers Tomcat, but if you're happiest in Windows World then you can use IIS Express fo free.
