The Windows Home Server team has released a minor software update for Windows Home Server
>> November 2008 Windows Update for Windows Home Server
This update improves the interaction between home computers running Windows Vista and a Windows Home Server-based system when copying files or folders that are larger in size than the free space available on the first (or primary) hard drive to a Shared Folder. Additionally, this update resolves certain issues which can happen when restoring files and folders from Windows Home Server, such as the opening of a Home Computer Backup sometimes stalling at 79% complete. The update also improves the search functionality when using remote access.
