Get windows username without using activex object

Question

is it possible to get clients windows username in asp.net hosted in remote server without using activex object ?

i have used following code

        Response.Write("HttpContext.Current.Request.LogonUserIdentity.Name  " & HttpContext.Current.Request.LogonUserIdentity.Name)
        Response.Write("<br/>")
        Response.Write("HttpContext.Current.Request.IsAuthenticated " & HttpContext.Current.Request.IsAuthenticated)
        Response.Write("<br/>")
        Response.Write("HttpContext.Current.User.Identity.Name " & HttpContext.Current.User.Identity.Name)
        Response.Write("<br/>")
        Response.Write("System.Environment.UserName " & System.Environment.UserName)
        Response.Write("<br/>")
        Response.Write("Security.Principal.WindowsIdentity.GetCurrent().Name() " & System.Security.Principal.WindowsIdentity.GetCurrent().Name())
        Response.Write("<br/>")

but it is always giving me server user name not the clients username .

Answer 1

You can try to use ServerVariables

string Hostname=Request.ServerVariables["REMOTE_HOST"];
string Username=Request.ServerVariables["REMOTE_USER"];

Answer 2

this line will work if you are using "Windows Authentication"

Response.Write("HttpContext.Current.User.Identity.Name " & HttpContext.Current.User.Identity.Name)
