Question

I have a ASP.NET application where an employee logs into Windows and then they have to select their name from a long list of names and log in into the application.

Answer 1

I was having an related issue where my local build was recognizing the WindowsIdentity.GetCurrent().Name.ToString() value as my Windows account name, but when I accessed the website via a server it was always "DefaultAppPool".

I was able to get this to work by doing the following:

1. Open IIS and navigate to my website.
2. Under the IIS sections, double click "Authentication".
3. From there, disable "Anonymous Authentication" and "Forms Authentication".
4. Enable "Windows Authentication".

From there I was able to discern the user id/name and proceed with my coding. I had to rework a little bit, but it was well worth it. Thanks for the advice!

Answer 2

Try this:-

System.Web.HttpContext.Current.User.Identity.Name

Also check this forum.

UPDATE:-

1) Please check that you have disabled anonymous mode in IIS

2) Also do check that you have set the application to autheticate the user details like this:-

 <authentication mode="Windows"/> 
    <authorization> 
       <allow users="*"/>
    </authorization>

or like this:-

  <authentication mode="Windows" /> 
     <authorization> 
        <deny users="?"/> 
     </authorization>

3) You can you can either configure IIS in Control Panel so that your site (or machine) uses Windows authentication and denies anonymous access
