Arrow SFC /scannow won't run
Win XP Pro

When I type SFC /scannow at the Start>run command line, a DOS window with C:\WINDOWS\System32\sfc.exe comes up briefly (< 1 sec) and exits. SFC never runs. I have looked in the registry and made sure that the sourcepath is pointed to C:\i386. I have also added the registry value to show the SFC progress bar. Anyone have any idea what's going on? Thanks.

Maybe pro is different but isn't I386 in the WINDOWS folder?

I'm a little confused. Are you trying to run from Start/Run/CMD? Run from Start/Run/ SFC /Scannow. If I'm misunderstanding you, sorry.

Sorry I didn't make myself clear. I am running it from: Start/Run/SFC /Scannow

I just double checked. It is in my root (C:\) folder.

Run it from a command prompt. Start, run, cmd, ok, sfc /scannow. If it exits, it will give you an error message. Right click my computer, choose manage, event viewer, and you should find the errors under system.

Maybe just try changing the registry to D:\ or E:\ to see if it will run at all temporarily, this may help you decipher if all the files are in the C:\I386 Folder you copied to your harddrive.

When I run sfc from the command prompt I get the message: you must be an administrator running a console session in order to use the Windows File Checker utility.

OK. Are you an Admin?

Where did the C:\i386 folder come from? Usually, sfc is run from the CD. That i386 is fine if it is the substitute for the CD that you have from the OEM, but not if it is backup files from the installation of SP1 or from some other source. Sfc needs the files that were originally used to install XP.

Can you log in as Admin? sfc /scannow will not work from the run prompt, it will do just as you say..appear and disappear. It has to run from command prompt.

I finally figured it out and just now read this message. You are correct. Apparently you have to be logged in to the Administrator account for SFC /Scannow to run. It will not run if you are logged in as another (not administrtor) user with administrator privileges. I added the Administrator account to the Welcome screen, logged in and SFC ran fine.

Thanks for all the comments.

Actually, sfc runs fine from any account with Admin privileges. It doesn't have to be the actual Admin account (except in your case). Any Admin account has all the Admin privileges with no exceptions.

And, sfc runs equally as well from the Run box as from a command line.

You may have some permissions problem on your account.

PS. You really don't need to add the Admin to the Welcome screen---Ctrl+Alt+Del (twice) will allow you to log in as Admin.
