Microsoft has released Windows Server Solutions Phone Connector for Windows Home Server 2011 for integrating Windows Phone 7 with your WHS 2011 server.
In a post at the Windows Home Server blog:
The Windows Server Solutions Phone Connector add-in enables you to connect to your home, business, or storage server by using your Windows Phone 7 phone. This document provides help for the integration of Windows Phone 7 into Windows Home Server 2011, Windows Small Business Server 2011 Essentials, and Windows Storage Server 2008 R2 Essentials.
After completing the integration of your Windows Phone 7 phone into a WHS 2011 server, you can use your phone to perform remote server management tasks (such as view alerts, manage users, and start and stop backups). In addition, with appropriate permissions, you can use your phone to view or access media files that are stored on the server.
While we don't see many people having both a Windows Phone 7 and a Windows Home Server-based server, it's nice to see that Microsoft is thinking of bringing new features to its customers.
