sfc /scannow not successful in repairing files

[Guest JaniceLynne]

I ran sfc /scannow yesterday - OS XP SP3, CD XP SP3. It completed without giving me any notifications other than a number of:

 

"Files that are required for Windows to run properly must be copied to the DLL cache."

 

I was prompted to click on 'retry'.

 

It lasted for around 40 minutes then closed.

 

I thought all had gone well until I looked in Event Viewer today. There are approximately 90 Windows File Protection entries there mostly with the following information:

 

The system file ........ could not be copied into the DLL cache. The specific error code is 0x800b0100 [No signature was present in the subject]. This file is necessary to maintain system stability.

 

 

I think the Help and Support Center that no longer functions properly was listed as being a bad file with a bad signature......and could not be restored to its original, valid version.

 

 

What do I need to do now please? Try again, try in Safe Mode or ? Please note I normally summon a computer technician for complicated work / reinstallation of Windows and I'm not able to do that at present.

 

 

Update

 

 

Just read this ?:

 

 

When you install Service Pack 1, your event viewer may contain many Windows File Protection (WFP) error messages, similar to the following:

 

 

The system file c:\winnt\system32\xenroll.dll could not be copied into the DLL cache. The specific error code is 0x0000000 \[The operation completed successfully.\] This file is necessary to maintain system stability.

 

 

The system file c:\winnt\system32\inetsrv\smtpadm.dll could not be copied into the dll cache. The specific error code is 0x00000002 \[The system cannot find the file specified.\] This file is necessary to maintain system stability.

 

 

The system file c:\winnt\system32\gdi32.dll could not be copied into the DLL cache. The specific error code is 0x800b0100 \[No signature was present in the subject.\] This file is necessary to maintain system stability.

 

 

This is a problem that was corrected in SP1, but the updated SFC.DLL for the System File Checker (SFC) doesn't function until restart.

 

 

You may ignore these errors.
