Dear All,

I am using the following code to get the NT ID for my intranet application




string CurrentUser1;
CurrentUser1 = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();
string[] Cuser1 = CurrentUser1.Split('\\');

Response.Write(@"<script language='javascript'>alert('ICICI USERNAME: \n" + Cuser1[1].ToString() + " .ICICI: \n" + CurrentUser1 + " .');</script>");

It is working fine in the local development system, But problem arises when I deployed on live it is taking the ID of the server and its toughing error.

Can any one let me how to get the client system NT ID .

Plz let me know how to solve this.
