BITS (background intelligent transfer service) not working

within the last week, BITS has stopped working.  I'm running vista ultimate 64 OS, with UAC turned off.

When i open up services and try to start BITS, i get the following error:

Windows could not start the Background Intelligent Transfer Service service on local computer.  Error 127: The specified procedure could not be found.

I've tried downloading the bits repair tool from microsoft.  When I try to run that, I get 'Background Intelligent Transfer Service (BITS) repair is not required currently.

I've verified that the service is set to start as Automatic (Delayed).

Execute this command
sfc /scannow
This will check your system files
then check that you have these services running:
COM+ Event System
Remote Procedure Call (RPC)
DCOM Server Process Launcher
Because BITS depended on this.

Thanks for the reply.  I ran sfc /scannow and rebooted.  I then checked all of those services and they were all running, however, BITS will still not run.

sfc /scannow indicated that some corrupt files were found, but could not be repaired.  I opened the CBS.log file and found the following line:
