Note: In typical Microsoft fashion, this article is titled to target Windows Server 2003 SP2, however both the error and the fix apply to x64-based Windows XP. It is not known if this error occurs on 32-bit Windows XP, and if your problem is a Storport driver on a 32-bit XP then there is nothing to stop you from trying the driver fix for 32-bit Windows Server 2003.
