i need to enable Windows Autenthication for a specific website on IIS 7.5

If I open "Autenthication" I just see 3 options:


Based on Form

ASP.NET Representation

(3 above translated by me, I have italian IIS)

I've been told that I should see also "Windows AUtenthication" in that list.

In "modules" for the same website I see "Windows Authentication", with code "System.Web.Secuitiry.WindowsAuthenticationModule", Module type is "Managed",and Type is "Inherited".

I am totally stuck.

Do you have the Windows Authentication feature installed for IIS?

In PowerShell:

Get-WindowsFeature Web-Windows-Auth

Is it installed? If not, then:

Add-WindowsFeature Web-Windows-Auth

Import-Package? – Ryan Ries Sep 4 '13 at 13:32
My bad, for some reason I thought that was necessary for the WindowsFeature cmdlets – Chris McKeown Sep 4 '13 at 13:38
I don't understand your answer. I tried to execute Get-WindowsFeature Web-Windows-Auth from Powershell but I get an error. – user193655 Sep 4 '13 at 14:40
And the error is? If you prefer you can install the feature from the GUI. – Chris McKeown Sep 4 '13 at 15:24
@ChrisMcKeown the error is in italian, anyway if you tell me plaese how to do from the GUI it would be great. Thanks. Ithought this was wasy to find by googling but i did not succeed. – user193655 Sep 5 '13 at 6:57
