The Release Candidate of the Windows Server Solutions Phone Connector for Windows Home Server 2011 (aka Integrating Windows Phone 7 with your WHS 2011 Server) is now available.
This connector allows you to use the Alert Viewer on your phone. It's the same Alert Viewer used on WHS 2011. The connector allows for better user management including a user-panorama item that performs basic user management tasks such as viewing user account details, enable or disable a user account, and change a user account password.
It also allows you to control the devices by viewing server-joined computer and Mac details, viewing the backup status that every device reported to the server, and start or stop a backup for any computer or the server. The connector also allows for discovery and viewing of media elements that you stored on your server in the appropriate shared folders (such as Music, Video and Picture shares).
You can also have a live-tile on your Windows Phone that showcases the count and type of network health alerts, percentage of storage use of your main disk, and server name.
