This is part of the Windows Error Reporting Dump Reporting Tool, and it is present in both Windows XP and Windows Server 2003. It shows as a startup item whose execution line usually reads as "KernelFaultCheck" %systemroot%\system32\dumprep 0 -k The switch or tool dumprep creates memory dump reports that you can send to Microsoft if you answer "Yes" when prompted to send such reports. This entry usually shows up for the first time after your system has experienced a Windows XP "dump" crash, or an Office XP or Internet Explorer 6 crash where you were prompted about sending the crash results to Microsoft.
