Windows Home Server Knowledge Base article

We just published a Knowledge Base (KB) article on Microsoft Help and Support:  “Editing files using certain applications may cause file corruption on a system running Windows Home Server (946676)”.  A few people in the Community Forums have reported data corruption when saving files from applications including Windows Vista  Photo Gallery, Windows Live Photo Gallery, Microsoft Office OneNote 2007, Microsoft Office OneNote 2003 and SyncToy 2.0 Beta.  Additionally some applications, like Microsoft Money and Microsoft Outlook, do not support storing files on shared folders.  As always, we’re using this blog to openly communicate important issues that may have an impact on the home server community.


The Windows Home Server team closely follows the threads on the Community Forums to get real-time feedback.   Data integrity is of the utmost importance; the Windows Home Server team tackles issues around file or data corruption with extreme seriousness and urgency.  When we see issues that we cannot reproduce (“repro”), we contact specific forum participants and initiate an e-mail conversation to understand the issues, environment and exact steps a user is taking.   We are releasing this KB because we have been able to successfully “repro” this issue.   For more information about our product support process, please see this post.

So, what’s next?

First, please read the Knowledge Base article #946676, and follow the recommendations.

Second, our development team is working full time through the holidays to diagnose and address this issue.  We will keep you posted on our progress on this issue as soon as we have more to share.

Thanks again for all of your support,

The Windows Home Server Team

    The knowledgebase article and/or this article needs to be less vague in its recommendations on what we users are alowed to do/not to do.

    Are we not allowed to edit or save any files using the specified programs on our PCs and then save/store them on WHS?


    is it that we are not to save/edit files that currently reside on the WHS from our PCs (using the specified programs)?

    As it stands, the kb article instruction is so imprecise one gets the impression that we’d be as well switching off the WHS until this situation is (hopefully) resolved. <confused>

    I hope they get this one fixed soon because it it doing no end of damage to the reputation of WHS in the wider community. Every tech forum is covering this story and WHS is being rubbished – just wait and see what effect it has on sales when news hits the mainstream press…

    I reported this during the Beta and had several back and forth responses. It’s a real shame MS didn’t listen and/or take action. BTW: I think Windows Movie Maker for Vista also has its files get corrupted with WHS.

    This HP WHS plugged in and worked perfectly.  Even my learning curve was minimal.  Using Vista U. all the network stuff was automatic.  Good Work!

    Only glitch so far is this Sync Toy thingy (and the mystery IE add-on that gives me a pretty blue but blank toolbar).  Help!

    Can you tell me if the following is related to this, or if it is another issue that I should be reporting somewhere?

    I am using SyncToy 1.4 (not v2 beta) to synchronise my photos folder on my PC with the photos folder on the server (since I don’t want to save my pictures to the server while the issue your blog post is about is ongoing!).

    When the synchronisation runs, about 50-75% of the photos are synchronised fine, but the remaining 25-50% are wrongly named, e.g. "Xmas Day 010.jpg_SyncToyBackup_20071227232850967" instead of just "Xmas Day 010.jpg".

    My Google search for SyncToyBackup reveals one discussion of a similar issue relating to anti-virus-type software intefering, but I think this is more likely to be to do with the server starting to balance its storage before SyncToy has had a chance to rename the file, or something – is this feasible?

    Should I be switching to SyncToy v1.2, or trying the beta v2.0, or can you advise on how to resolve this issue while sticking with v1.4?

    Thanks in advance for any help you can offer.

    Can you tell me if the issue with Synctoy is only when copying TO the WHS?  I recently installed the Synctoy beta and use it only to copy from the WHS onto an occasionally used computer for backups of my shared folders.

    Shortly after I installed Synctoy the server started having significant issues.  I finally fixed the issue by replacing the RAM in the WHS.  This doesn’t sound like the same problem, but just throwing it out.
