string NtAccountName;
NtAccountName = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();

since you haven't set any authentication on Default2 page you will not get the name here

System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString()

so changes are here

default2.cs

Response.Redirect("Default.aspx?txtBxUser.text");
 
to

Response.Redirect("Default.aspx?u=txtBxUser.text");


default.cs

string NtAccountName = Context.Request.QueryString["u"].ToString();

Sorry comes back as NT AUTHORITY\NETWORK SERVICE
I tried something close to it
         WindowsIdentity currIdentity = WindowsIdentity.GetCurrent();
        string NtAccountName = currIdentity.Name.Substring(currIdentity.Name.IndexOf("\\") + 1);

This gave me Network service
I need the value of txtBxUser from the login form

The error I get now is
System.Web.UI.WebControls.TextBox' does not contain a definition for 'text' and no extension method 'text' accepting a first argument of type 'System.Web.UI.WebControls.TextBox' could be found (are you missing a using directive or an assembly reference?)
