How to run a Windows File Protection scan in safe mode on XP ???


It seems it is not possible to launch a Windows File Protection in safe mode in XP.

Normally, it should write :  sfc \scannow

but in safe mode, it says that

The error 0X000006ba occurs when the RPC server is unavailable. In the safe mode, the rpc service cannot be started.

I have done long search in google, and i have done all what i found like

run rpc service
install trusted certificate
Enable the System File Checker in registry

but it seems impossible to start sfc scannow in safe mode in xp

I would like to know if it is true

This question came up back in 2007 and no solution to the RPC issue was found.  You could try nobus's comment about running SFC in Safe Mode with Command Prompt, but since the RPC service does not start in Safe Mode the chances of success are slight.

(RPC is, in fact, a service that does not run in Safe Mode.)

Here is how to run it from the recovery console of an XP installation CD:

Or, I do believe it will run if you choose Safe Mode with Networking; but, I don't believe it will work in plain Safe Mode.

user named linney say:
Even though the RPC Service is started and running in Safe Mode, I have never understood this error when trying to run SFC /Scannow from Safe Mode,

"Windows File Protection could not initiate a scan of protected system files.

The specific error code is 0x000006ba [The RPC server is unavailable.]."

Maybe there is something in what Bill says?

Maybe someone can explain or clarify that error?

I attached a screencapture to show that rpc service is started in safe mode

I thought I smelled a rat!  That PC is either still infected or is suffering from the effects of an infection and SFC has been disabled.  Here is how to fix that:

I; though, would heartily suggest you run Roguekiller, TDSSKiller, and ADWCleaner to clean or confirm the PC has been cleaned before running SFC.

And, I'll bet there is significant damage to numerous services and permissions.  While not a magic bullet,'s all-in-one repair tool often works wonders! (but, not before the PC is clean)
I would check the box to repair file permissions before running the repairs.

Windows File Protection is disable in safe mode even if networking is chosen
