may help you . If you're on .NET 4.5 or higher, just use the System.DirectoryServices.AccountManagement namespace and the UserPrincipal class in that context:
code :
// you'll need to add a reference to this .NET assembly in your project
// so that you can use this namespace
using System.DirectoryServices.AccountManagement;

public string GetLoggedInUser()
    // establish the PrincipalContext - this will grab the default domain, default containers
    using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
         // get the currently active user
         UserPrincipal currentUser = UserPrincipal.Current;

         if (currentUser != null)
             // this will return "first name last name" separated by a space,
             // e.g. "John Doe" or "Jane Tarzan" 
             return $"{currentUser.GivenName} {currentUser.Surname}";

    return string.Empty;

To fix the issue you can do EDITED: If I understand your situation properly, then you might be going about this the wrong way.
When your app starts up, you could do a simple ping against a machine that the user would only be able to see if they were connected to your network, whether they log into the local network or if they are connected via the VPN.

help you fix your problem Just move your code into methods or classes (whatever fits best) with the required arguments. here is your modified version in C# :
code :
 // ConnectionString make it globle access inside this class
    private string ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString;

    protected void PopulateReviewerDDL()
        // Currently logged in user:  
        var iUserName = GetCurrentUser();

            var reviewerName = GetReviewerName(iUserName, ConnectionString);

            if(reviewerName != null)
                lblUserName.Text = reviewerName;

                if (!ddlReviewerName.Items.FindByText(reviewerName) == null)
                    ddlReviewerName.Text = reviewerName;
                    Response.Redirect("NoAccess.htm", false);
        catch (Exception ex)

    protected string GetCurrentUser()
        return Right(Request.ServerVariables("AUTH_USER"), (Request.ServerVariables("AUTH_USER").Length - 6));

    protected string GetReviewerName(string username, string connectionString)
        if (string.IsNullOrEmpty(username) || string.IsNullOrEmpty(connectionString))
            throw new ArgumentNullException("Username or ConnectionString is Empty");

        string fullName = null;

            using (var connection = new SqlConnection(connectionString))
            using (var command = new SqlCommand("SELECTADISNames", connection))
                command.CommandType = System.Data.CommandType.StoredProcedure;
                command.Parameters.Add("@LogonName", SqlDbType.VarChar).Value = username;

                using (var reader = command.ExecuteReader())
                    while (reader.Read())
                        fullName = reader["FirstName"].ToString() + " " + LastName = reader["LastName"].ToString();

        catch (SqlException ex) // we need to catch sql errors only 
            throw new Exception(ex.Message);

        return fullName;

I wish did fix the issue. As stated in your question, IE has to be configured to allow Windows Integrated Authentication. Doing so basically gives IE permission to provide your credentials/token to sites that request it (usually limited to sites in the Intranet zone). Note that your web site will have to request those credentials (in IIS it is as simple as checking a checkbox). In Apache you'll have to find an Apache module that add NTLM authentication support to your web server. A quick Google search revealed a few different modules, none seemed particularly up to date. If you get an Apache NTLM module working, I suspect you'll be able to access the username via$_SERVER['AUTH_USER'].

should help you out There is no such thing as "Active Directory User". When you authenticate with a Domino server you always get a "Domino user" regardless of what you authenticated your user against. I would suspect that the AD is delivering a "Domino user" name on authentication which can look different from the AD credentials depending on your configuration. So your course of action would then be a LDAP lookup into AD to get the matching AD user.

it helps some times AD doesn't support it. You may be able to pull the info from the Event Logs on the DC's if you have auditing on. I've also seen people use a logon script to write a value into the extensionAttributes of the AD account. The other option is to reach out to each computer and query the currently logged on user for each of them.
