At CES 2011 in Las Vegas, Microsoft unveiled a new Windows Phone 7 add-in for Windows Home Server Code Name "Vail".
Here's how it works:
The WinP7 add-in creates a new feature on your WP which's currently called, "My Server". The WP feature requires a WHS "Vail" setup and running with the Remote Web feature enabled. Selecting, "My Server" brings the first setup screen asking to add home server connection information. Clicking "add an account" starts the simple setup wizard.
Enter your WHS's Domain name and click Submit. Once submitted, you're requested for username and password. The user account info needed here is the same that you would use to access WHS's shared folders inside your home. You also have additional option to add Admin Access. Adding admin's access will enable you to see your WHS's network alerts.
After inputting required info, click "Sign In". If you've entered all the info, including Admin, you should have 3 screens that you can scroll across; Alerts, Media & Account. Without Admin Access enabled, you'll only have 2 screens; Media & Account.
Just like Alert option on Dashboard, you'll be presented with all Alert Notifications on your WHS. The Alert info is populated with same details the Dashboard would provide. The WP7 will display info on the issue at hand and possible ways to resolve the problem.
If you dig further, you're given the ability to Disable/Enable the alert and to even try and repair (when possible -- for e.g., router issue).
With all your music, photos and videos placed on your WHS, you can select any of the 3 options, you're presented with your library of content. Smooth streaming music, photos and even videos right from your home to your mobile device away from home!
The account screen presents you with ability to logout of the WHS Add-in.
The WP7 "My Server" app also adds an option under picture sharing. This option will upload pictures to your home server if selected as long as you'e still logged in! Start by taking a picture with your phone and opening the options.
After opening the option menu, select "share" to open the sharing options. Tap "upload to My Server" and let your WP7 handle the rest!
The WP will create a new folder with its "phone name" called Mobile Uploads within the WHS pictures folder. Inside this folder, you can view all the photos you have uploaded from your phone both inside and outside your home.
