win xp defrag will not run

[Guest]

I am using win xp home w/sp1. When I start to defrag, I get a error window,
stating corrupt cryptdlg.dll, or dinput.dll, or digest.dll. What is the
easiest way to fix the files.
Thanks for your help

open C:\windows\system32\dllcache (thats a hidden folder, unhide it or type
the address into start menu - run) and copy the files out of there into
C:\windows\system32\wbem and into C:\windows\system32\ and into the media
player directory (probably C:\program files\windows media player)
