Logon required (before showing my 'logon' page!)

I'm moving my web site from another host to Winhost. I don't want to cut over the DNS until I'm sure it's working properly.

When I use the 'Secondary FTP' to test the site, I'm immediately presented with a "Windows Security" logon screen saying;
The server xxxxx.w01.Winhost.com at xxxxx.w01.Winhost.com requires a username and password

I need to give my Winhost ID and Password in order to get to the requested form - which is my logon form!

Thoughts?

In case it helps, here's (most of) my web.config;

Code:

...But I want to use forms authentication, basically allowing visitors to only see my logon page until they're authenticated...

Code:

    <authentication mode="Forms">
      <forms loginUrl="~/Forms/Authenticate/Login/Login.aspx" timeout="2880" />
    </authentication>

I have 'Page Load' events in every other form redirecting them back to my login form if they're not authenticated. (I also don't see a way to enable "Anonymous Login" - unless you're suggesting that I change the above to <authentication mode="None">

 

Thanks

Excellent. Thank you.
