If you are logged on as a member of the Administrator Group it will accept
the password you use to log on to Windows. Otherwise you need to use "The
Administrator's" password. if you have not set one it is probably blank.
Setting the schedule for DiskClean is not completely straight forward as you
have to specify the volume to be defragmented if you do not know the
switches I suggest you look at this guide
http://www.tweakhound.com/xp/tasks/sch_disk_cln.htm
Setup the schedule and enter the password. Close the scheduler, then right
click on the task you have just created. If (the exe file is in
%SystemRoot%\System32\cleanmgr.exe). If it starts then you are Ok stop it
and close the scheduler and disk Clean will run at the time you chose on the
volume selected. If it does not start you have not entered the correct
password and you have got to try again until you put in the right one.--
