Question

I am building a small intranet app in which I need to display the user name of the person who opens the webpage.

I tries with:

WindowsIdentity.GetCurrent().Name.ToString();

But this always displays my user name on the webpage.

Answer 1

Please see THIS – basicaly you need to enable Integrated windows authentication and the use one of the following:

System.Security.Principal.WindowsPrincipal p = System.Threading.Thread.CurrentPrincipal as System.Security.Principal.WindowsPrincipal;    
string strName = p.Identity.Name;

or

string strName = HttpContext.Current.User.Identity.Name.ToString();

or

string strName = Request.ServerVariables["AUTH_USER"]; //Finding with name    
string strName = Request.ServerVariables[5]; //Finding with index

All 3 cases should retrun a string containing DomainName\WinNTLoggedUserName.
