getting active directory username

i have solved the problem by using hostname instead of ipaddress of the server. the windows dialog box for authentication disappears

that is already done

in that case, remove the Annonymous checkbox in the IIS Security Tab.

Well the username is for finding that in ultimus to see that it exists there,if it is there then it will be authenticated.We are building an intranet base application with windows server 2003 and windows xp pcs as the client.

I will try your setting in my office as the active directory is there.

The thing is that will it result in some popup box for authentication first with the iis?. Then it will display the username. (because it is doing just as i have said) and that i don't want to display any popup box. When I type the address of my application in the browser as I am already login in the domain it should just bring the username there,not first i reauthenticate in that popup box and then it brings in the username. I hope it is clear more now.

Hi

You can u get like this way

private bool Authenticate(string userName,
    string password, string domain)
{
    bool authentic = false;
    try
    {
        DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain,
            userName, password);
        object nativeObject = entry.NativeObject;
        authentic = true;
    }
    catch (DirectoryServicesCOMException) { }
    return authentic;
}

thank you

well i dont quite understand why you need the UserName, since you only need to set in web.config Authention= Windows

and set the IIS Folder Security to Windows authentication


but if you need it use "Enviorment.UserName"
