Looks like we've got a definitive answer to "How would you change Windows Home Server?" -- make it so it doesn't corrupt data. Microsoft has just posted a Knowledge Base document saying that it's confirmed WHS corrupts various files when saved to the server by certain apps. The bug affects several MS apps, including Money, Outlook 2007, Vista Photo Gallery, Live Photo Gallery, and SyncToy, but it also hits Quicken, Quickbooks, and -- fatally for a media server -- BitTorrent clients. Microsoft says it's working on a fix, but that in the meantime, you should avoid using WHS with these apps.
