I tried using the following codes to get my clients info (MyDomain\Username):
HttpContext.Current.Request.ServerVariables["LOGON_USER"];
HttpContext.Current.User.Identity.Name.ToString();
Page.User.Identity.Name.ToString();
All of them works fine, well atleast on my localhost. But when i deployed it in our server, and tried to access it in our intranet those codes return the info of the SERVER Machine, not the client's machine.
PS: the authentication mode is Windows and The IIS is also in windows auth...
