Accessing to website remote in C# on the private company network with VPN connection

Question

Hello there, I need your help

I have published a new ASP NET C# web site on the private company network.

This new web site works on a windows server 2012 server and this is the authentication method for access to web site :

public void Authentication()
{
    string username = Page.User.Identity.Name.ToLower();
    string[] strUsername = username.Split('\\');

    if (strUsername.Length > 0)
    {
        username = strUsername[strUsername.Length - 1];
    }
}

But I have problem to accessing when I'm connected from my house using VPN connection, because the website not validate my access as if not identify the variable :

string username = Page.User.Identity.Name.ToLower();

The access on the private company network is with server proxy, the access on the VPN connection don't use server proxy.

The administrator of private company network says it's not a network problem.

I have tried in windows server 2012 server setting IIS property Authentication without success.

I verified that when I connect with VPN the user recognized by Page.User.Identity.Name.ToLower(); is always "administrator"

I have tried with ASP Classic webpage and :

1. If I connected on the private company network the output is :

AUTH_USER: Domain\Username
LOGON_USER: Domain\Username
REMOTE_USER: Domain\Username

     2. If I connected with VPN the output is :

AUTH_USER: ServerName\administrator
LOGON_USER: ServerName\administrator
REMOTE_USER: ServerName\administrator

How to do resolve this ?
