One of my clients has an SBS2008 server and use Nokia mobiles to connect to their exchange accounts. This has been working fine for the past couple of years, but after a server reboot last month it isn't working. The Nokia's are just coming up with a certificate error, not giving me a chance to install a new certificate or ignore it. I have run https://www.testexchangeconnectivity.com/ and it fails here: Testing HTTP Authentication Methods for URL https://remote.companyname.co.uk/Microsoft-Server-ActiveSync/. The HTTP authentication test failed. Tell me more about this issue and how to resolve it Additional Details The Initial Anonymous HTTPS request didn't fail, but Anonymous isn't a supported authentication method for this scenario. does anyone know what this means? and how to resolve it? Also, OWA is not working, i am getting this error; 404 - File or directory not found. or from the server: Error Summary HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

The URL contains a typographical error. A custom filter or module, such as URLScan, restricts access to the file.

Is this website works fine within the network?Shaba

no i cannot access the website from inside the network

Can you please let me know the error message you are getting internally?Shaba

If you look in the original post you will see that trying to access OWA brings up a 404 not found error

that means a server reboot deleted the owa virtual directory? are u able to see owa virtual directories exists in your server? otherwise do onething recreate the default site http://exchangeshare.wordpress.com/2008/07/16/how-to-recreate-owa-virtual-directory-exchange-2007/ thanks rajah
