System File Checker Not Working

Asked By 410 points N/A Posted on -


I have run sfc /scan now on command prompt to check and ensure if there’s an error with my Windows XP Professional. But when I typed on the command prompt, nothing happens. I opened the Run command then type cmd on it, then type the exact command sfc /scan now.  I tried doing it as the administrator but nothing happened. Every time I hit the enter key, the cursor will go down but it is not scanning. I tried to reset the SFC to its default, by typing sfc /scannow REVERT, but it does not change a thing.  Sometimes this error appears; The RPC server is unavailable, but sometimes the cursor will just go down to the next line on the command prompt. How can I fix this? I want to ensure that my system is running correctly. And what does RPC server is unavailable means?

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

Windows resource protection could not start the repair service.

You must be an administrator running a console session in order to use the sfc utility.

Here are my computer’s specifications:

Acer Aspire M1830

Processor: Intel Pentium Dual Core 3.0 GHz


Display: Intel Graphics Media Accelerator

Hard Disk Drive: 320 GB

Operating System: Windows XP Professional

Anti Virus: ESET Smart Security

Default Browser: Mozilla Firefox

I never tried running SFC before. 

My friend just advice me to run this to correct all the errors and missing drivers on my computer.

Please send me detailed instructions.

Thank you.

  • Since you've tried to run the sfc /scannow command as an administrator and nothing happened,
  • you should start thinking of others reasons for the problem.
  • Your system is probably infected ; CodeRed malware could be the reason.
  • So try this:
  • 1. Open the registry typing Regedit and then navigate to this key:
  • HKEY_LOCAL_MACHINE SOFTWARE Microsoft Windows NT CurrentVersion Winlogo
  • 2. Check the SFCDisable key and verify its corresponding value is set to 0 (Zero) – else change it to 0 –
  • 3. Restart your computer and execute the SFC/ Scannow program again.
  • Tell us if this has fixed the problem

Thank you for helping. But I am not advanced when in terms of fixing registry keys.

Your solution is very helpful, but instead of going to my registry, I tried restoring from an earlier point, and it works.

And for added solution, I scanned my whole system and delete all the cookies and everything.

No virus detected.
