Windows Home Server was initially released with a lot of fanfare, and for the most part, it has received positive reviews. The good doesn't come without the bad, though, and back in December a serious data corruption flaw came to light. No workarounds were available then, but it was thought the scope of the problem was small.
Now, it seems, the problem is actually more widespread than initially thought. More problems have been discovered related to data corruption, with the list of affected programs growing. Programs from iTunes and Windows Media Player, to Winamp and Excel, have been pointed at as potential sources of corruption. There is still no fix from Microsoft. They are obviously aware of the problem, but even they say they are just researching the problem and have no fix or ETA on a patch yet. According to some, the impact might be a system-wide one, and could affect any program that accesses data on the WHS machine.
