Hi --

We have the computers on our home network (all of them WinXP Home SP3) set up to implement "poor man's disaster recovery": all of our machines are set up so that the default directory for data files for applications critical to work and school (eg, Word, Excel, Powerpoint docs) is each user's home directory on a single machine -- and that machine runs 2 scheduled tasks (at 4 am and 5 am respectively) to copy any changes in those directories to a backup copy on each of 2 other machines. Short of a disaster that destroys all of the machines simultaneously, that gives us reasonable and inexpensive recovery from inevitable disk crashes.

The scheduled tasks that do the copying run as one of the users on the main machine (a user account present on the backup machines as well). WinXP Home seems to require that that user account have a nonblank password (on the main machine) in order to run scheduled tasks.

I notice that I am unable to run sfc /scannow as that user, even though that user is an administrator.
I get the message:
You must be an administrator running a console session in order to use the Windo
ws File Checker utility.

I *am* able to run sfc /scannow as another user that is an administrator, but does not have a nonblank password.

Any idea why this is so? What's going on here?

TIA
-- Phil

Hi -
Just a quick observation , do you insert the XP CD when you try to run the System File Checker as you do not mention this -

Thank You -

The behavior I describe happens regardless of whether the XP Home CD is in the drive or not.
The error message is output before sfc ever even looks at the CD drive.

Have you tried creating a new user account (with password) and seeing if it can run sfc /scannow?

If so, it could be a corrupt profile issue.

Good suggestion -- thanks!
I tried that, and it can.
So the problem appears to be with this specific profile.

Any idea how to discover what exactly is damaged, or how it was damaged?
How can I fix it?
Is there a way to check and repair a corrupt profile?
Is there an automated way to transfer the contents/settings of the existing profile to a new profile?

Hi -
Now that you have run sfc on the other account , will it run on the first account you attempted to run it -
The next item can be a check disk scan to see if there are general errors that can be repaired -Copy and paste the code below into Run Box and it will do the full 5 stage disk check and try to repair any faults it can find -
CMD /C ECHO Y|CHKDSK C: /R | SHUTDOWN /R /T 30
Close all open programs and the code will automatically reboot 30 seconds after you press OK - It will take (on average) 30 to 45 mins to run , so do not try to stop it once started -
Thank You -

AFAIK, you don't repair damaged profiles...just create a new one and move the settings/files per MS guidance...then delete the old.
