I would like my asp .net web application to only allow users belonging to DomainName\Domain Users to access the site. Right now I have "Anonymous access" disabled and "Windows Integrated Security" enabled on IIS. I also have the following code in my web config:
<authentication mode="Windows" />
<authorization>
<allow roles="DomainName\Domain Users" />
<deny users="*" />
</authorization>
When I attempt to access the website it prompts me for the username and password to connect to webserver.example.com. I am a member of the domain users group but it does not allow me access. What am I doing wrong either in the syntax or in my IIS settings?
Is Anonymous Authentication Disabled in IIS ? Only Integrated Windows Auth should be enabled on the web application.
EDIT from comments:
I see you have Anonymous disabled. Try adding <identity impersonate="true" /> within <system.web> and see if your behavior changes.

Some resources (images) don't appear when I visit the main page after login (using form authentication)
However, setting the attribute of anonymous authentication to 'application pool id' in iis manager works
what windows account is used for form authentication in iis?
Only the login Page need anonymous authorization access. It sounds like you didn't set anonymous authentication correctly.
When we implement form authentication in IIS, Both form authentication and anonymous authentication are enabled side-by-side. Then we will create allow auth rule for all user and deny anonymous user in site level.
<authentication mode="Forms">
<forms name=".MyCookie" loginUrl="Login" protection="All" timeout="60" />
</authentication>
<authorization>
<deny users="?" />
<allow users="*" />
</authorization>
Secondly, we need to create a authorization rule to allow anonymous access to login page.
<location path="Login">
<system.web>
<authorization>
<allow users="*" />
</authorization>
</system.web>
</location>
When you pass the form authentication, IIS will send a form authentication cookie with the username which is decided by your application. It can be a key in appsetting or a username from database.
1.
FormsAuthentication.SetAuthCookie(UserInfo.UserName, false, FormsAuthentication.FormsCookiePath);
2.
FormsAuthenticationTicket
3.
FormsAuthentication.RedirectFromLoginPage(UserInfo.UserName, false);
You need to make sure the auth_user and application pool identity have permission to access the image sources.

I have ASP web site using Windows Authentication.
Here are the web.config settings
<authentication mode="Windows" />
<identity impersonate="true" />
<authorization>
<allow users="*" />
<deny users="?"/>
</authorization>
When I host the website in IIS 6 the user never gets authenticated so Request.IsAuthenticated is always null in Application_AuthenticateRequest method. Same about the identity of the CurrentPrincipal.
The weird thing is that when I switch the website to use Visual Studio Dev Server, everything works brilliantly.
I have Integrated Windows Authentication ticked in the IIS web directory settings.
What am I doing wrong? Any help or advise will by much appreciated.
I am running Win7, IIS7, and have put together a website for an intranet using Windows Authentication. When I type in my IP for my URL I am able to access the website but other users logged into the intranet are unable to see the site. IE simply gives them a 'Website cannot be displayed'.
Below is the website's webconfig where I'm impersonating and have Windows as the Authentication mode.
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<identity impersonate="true" />
<authentication mode="Windows"></authentication>
</system.web>
</configuration>
Are there any read permissions that I'm missing?
Below are the current users and groups that have access to the site:
IIS_WPG
Administrators
USERS(myusername\Users)
IIS_IUSRS(myusername\IIS_IUSRS)
The users group should be a domain level Users group. It looks like you're currently only allowing local users
Ex:
USERS(mydomain\Users)
Don't you need a username and password in the impersonate area? or maybe not because you have windows authentication...
<identity imersonate="true" username="someUser" password="somePassword" />
I have a web application and I want to provide anonymous access to a couple of the web services in it so that we can access the web services from computers without a windows login on our network.
I've tried the stuff here Disable authentication on subfolder(s) of an ASP.NET app using windows authentication. I've done this:
<authentication mode="Windows" />
<authorization>
<deny users="?" />
</authorization>
...
<location path="Tests/QService.asmx">
<system.web>
<authorization>
<allow users="?" />
<deny users="*" />
</authorization>
</system.web>
</location>
These both "work" in that they allow access to the web service for anonymous users. However, it seems that IIS still sends an authorization challange because when I access the service from a browser I get a box to enter my username and password. If I hit cancel I get access to the page anonymously. However, some of our clients don't handle this well and just fail because of the 401 return code.
Is there a way to completely disable the windows authentication on that single location such that IIS will not try and establish a windows authentication?
You need to disable Windows Authentication on the Virtual Directory for that single location. Then you shouldn't be challenged.
I'm currently working on a page within one of my company's internet sites that is in response to some production issues we have. The page will be published with the rest of the web site to our DMZ, however I'd like to set-up some quick authentication so only users on our domain (assuming they access the site internally) can access the page. I'd like to use Windows authentication to do so.
Is there a quick way to accomplish this?
If I understand the question correctly, you want to enable security just on one page in your application - not the entire app.
Under IIS, you can manage the security settings on a page by page basis. In the IIS manager, pick the page, and change the security settings so that anonymous is off, and only Windows auth is accepted. You should get prompted for a login when you visit that page.
From Scott Gu's blog
To enable Windows Authentication
within an ASP.NET Application, you
should make sure that you have
“Integrated Windows Authentication”
(formerly called NTLM authentication)
enabled within IIS for the application
you are building. You should then
add a web.config file to the root
directory of your ASP.NET application
that contains an
section which sets the mode to
“Windows”.
You should also then add an
section to the same
web.config file that denies access to
“anonymous” users visiting the site.
This will force ASP.NET to always
authenticate the incoming browser user
using Windows Authentication – and
ensure that from within code on the
server you can always access the
username and Windows group membership
of the incoming user.
The below web.config file demonstrates
how to configure both steps described
above:
<configuration>
<system.web>
<authentication mode="Windows" />
<authorization>
<deny users="?"/>
</authorization>
</system.web>
</configuration>
EDIT:
You can apply the auth settings to just a path in this way:
<location path="mypath.axd">
<system.web>
<authorization>
<allow roles="MyRole, AnotherRole" />
<deny users="*" />
<deny users="?" />
</authorization>
</system.web>
</location>
You can simply use Windows Authentication settings in IIS. Just turn off Anonymous Access in IIS and set your NTFS permissions on the Web folder to the users whom you want to have access to the site. Your IIS admin should be able to handle this quite easily.
