Error 0x6ba (RPC server is unavailable) when running sfc /scannow on Windows XP in Safe Mode

Question

I think that my mup.sys file is corrupt. I received the following error when trying to access a network share that was located on my Windows 7 box, from my Windows XP box:

No network provider accepted the given network path.

After reading this I attempted to follow the directions by rebooting my computer into safe mode. After I run "sfc /scannow" I receive the following error message:

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

When I go into Services, it says that the Remote Procedure Call (RPC) service is running but that the Remote Procedure Call (RPC) Locator is not running. When I try to start the Remote Procedure Call (RPC) Locator, it gives me an error saying:

Error 1084: This service cannot be started in Safe Mode

What can I do about this? If it can't find the Remote Procedure Call service in safe mode?

Answer 2

The answer above points to a solution which does not mention that we want to launch sfc in safe mode.

I have also tried the /scanonce option, hoping if it can't run sfc in safe mode, at least it can program it for reboot. Same error messagage.

Answer 3

Add missing key SfcScan in windows registry, with DWORD value = 0x2 (this is for scanonce option). Worked for me.
