SYMPTOMS
When you use certain programs to edit files on a home computer that uses Windows Home Server, the files may become corrupted when you save them to the home server. Several people have reported issues after they have used the following programs to save files to their home servers:
 * Windows Vista Photo Gallery
 * Windows Live Photo Gallery
 * Microsoft Office OneNote 2007
 * Microsoft Office OneNote 2003
 * Microsoft Office Outlook 2007
 * Microsoft Money 2007
 * SyncToy 2.0 Beta

Additionally, there have been customer reports of issues with Torrent applications, with Intuit Quicken, and with QuickBooks program files. Our support team is currently trying to reproduce these issues in our labs.

Make sure that you have a backup copy of any important program files before you store these files on a system that is running Windows Home Server.



CAUSE
This issue may occur because of a recently discovered problem with Windows Home Server shared folders and with certain programs.



STATUS
Microsoft is researching this problem and will post more information in this article when the information becomes available.

Until an update for Windows Home Server is available, we recommend that do not use the programs that are listed in this article to save or to edit program-specific files that are stored on a Windows Home Server-based system.

The third-party products that this article discusses are manufactured by companies that are independent of Microsoft. Microsoft makes no warranty, implied or otherwise, about the performance or reliability of these products.

Update as of December 28, 2007
This issue affects only Windows Home Server. This issue does not affect any other versions of Windows Server or Windows Small Business Server. The problem is now reproducible with an automated test harness that was built over the last few days. You must be able to successfully reproduce (repro) an issue before you can create and test a fix for that issue. These issues occur in the following scenario:
 * A home server is under an extreme load. For example, lots of files are being copied to the home server.
 * At the same time, a user is editing files that are already saved in a shared folder on the home server.
 * The program that the user is using to edit these files is one of the programs that are listed in this article.

Although this Knowledge Base article was first authored before the team could consistently repro the issue and provide more specifics, the Windows Home Server team thought it was important to make people aware of it. For now, please follow the advice in this section and do not use the programs that are listed in this article to save or to edit program-specific files that are stored on a Windows Home Server-based system. You can still use the Windows Home Server home computer backup to back up and restore files from and to your home computers.
