Hi, I kind of found a way to make this possible.
First follow the instructions on this page to create a custom login page.
Then you would have to play a little bit with the login module settings. Go to Advanced Settings->Header and add the following code:
<script type="text/javascript">
$(document).ready(function(){
//hide the default login section
$("#dnn_ctr677_Login_DNN").hide();
//show the windows login section
$("#dnn_ctr677_Login_ActiveDirectory").show();
//remove class 'LoginTab' and 'LoginTabSelected' to the 'Standard' button
$("#dnn_ctr677_Login_DNN_l").removeClass("LoginTab");
$("#dnn_ctr677_Login_DNN_l").removeClass("LoginTabSelected");
//add 'LoginTab' class to the 'Standard' button
$("#dnn_ctr677_Login_DNN_l").addClass("LoginTab");
//remove class 'LoginTab' and 'LoginTabSelected' to the 'Windows Login' button
$("#dnn_ctr677_Login_ActiveDirectory_l").removeClass("LoginTab");
$("#dnn_ctr677_Login_ActiveDirectory_l").removeClass("LoginTabSelected");
//add 'LoginTab' class to the 'Windows Login' button
$("#dnn_ctr677_Login_ActiveDirectory_l").addClass("LoginTabSelected");
});
</script>
This will make the windows login active by default, just make sure the element ids and class names match with my code's.
Let me know if it works,
