rundll32 not valid app - XP Pro

Archived from groups: microsoft.public.windowsxp.configuration_manage (More info?)

This message appears as though your HD may be corrupt or Windows is missing
files needed to run. I would do the following steps; First run a Hard Drive
check to verify your drive is okay. Second: I would insert my Windows CD and
goto start click on run, in the run line type "sfc /scannow"
This will run a check on Windows files to verify they are not corrupt or
missing. Finally the last step would be to boot from your WIndows CD and run
a chkdsk /r while in console mode.

Hope this helps
