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

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

2

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

In Above 3 Cases returning string contains DomainName\WinNTLoggedUserName

(for Ex: Microsoft\Bill.Gates. Here Microsoft is domain Bill.Gates is Logger User Name )

Using string operations seperate the DomainName and UserName.
