SFC problem - "Windows Resource Protection could not start the repair service"

Question

We are trying to attempt to fix a Windows 2008 start up problem. We boot the machine from a Windows 2008 CD and go to the repair tool - command prompt.
When we do the command sfc /scannow, we are getting
"Windows Resource Protection could not start the repair service"
We did some researches there someone suggested the trustedinstaller is not running so we tried to do a net start trustedinstaller.
But We are getting
"The windows modulers instaler service is starting
The windows modulers instaler service is starting could not be started
A system error has occured
System error 1067 has occured
The process terminated unexpectedly. "
Anyone can give us an idea to see why we can not run the sfc the first place. Thanks

SYMPTOMS:
All attempts to run command:
sfc /SCANNOW
keep returning the following message:
"Windows Resource Protection could not start the repair service"
SOLUTION:
If you are using any kind of boot image/disk to boot up, you will have to use the "offline" switches (OFFBOOTDIR & OFFWINDIR) along with the SFC /SCANNOW command in order to start repairing your instalation properly.
please remember to tripple-check for corret partition letters, because this is a crucial parameter for SFC to start working properly.
also make sure to confirm whether so called "recovery" partion exists in your specific scenario or not. If so, in most cases this will render the "recovery" partition being the one to be set as a boot partition (OFFBOOTDIR) within sfc command, while Windows
system folder (OFFWINDIR) will actually reside on a different partition.
My scenario is described exactly above and therefore in my case boot partition letter was C: and system partition was D: ...As of that - the proper command line to run SFC successfuly was:
sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows
Successful scan for integrity of all protected system files and replacement of incorrect versions with correct Microsoft versions then looks like this:
X:\sources>sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\WindowsBeginning system scan. This process will take some time.Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.logwindir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log
Once SFC scan completed, I have run the Startup Repair from the repair dialogue menu prior rebooting the system. Remember to click "Cancel" on the prompt for using the System restore in this step. I am assuming you have tried this already time ago and confrmed
it did not resolve the problem, but most importantly - you really would not want to overwrite the files, which you have just repaired with any possibly corrupted ones ;)
After this I've unplugged bootable USB key with the My Windows Vista Enterprise 64bit setup disk image and restarted computer. System booted up properly on first attempt. No issues have been identified as a result of my post boot checks. This completely
resolved the issue in my case. Should you have questions, please let me know.
