Can't Get sfc /scannow to complete
Saturday, January 7, 2012 by BigDogBigFeet | Discussion: Personal Computing
I'm looking for some pointers to get sfc to complete a scan.
It runs the Verification phase to 16% the aborts with:
"Windows Resource Protection could not perform the requested operation"
I've tried disabling alot of startup programs but not all. I searched and found MS Help topic stating make sure Windows Moduler Installer is running and it is. I also tried turning off UAC.
So far no soap.
I'm running Windows 7 Home Premium 64
Any pointers.

Please read this:
The problem is the first fix (work around, actually) MS put out for the "Duqu" virus/Trojan.
If you installed the first one, go to http://support.microsoft.com/kb/2639417
and disable it. Then run your sfc /scannow. Offline. then re enable it. Bet that solves your problem. That's what happened to me.
You might have to roll back part of Security Update MS11-100 but don't do that until you try what I suggested re the duqu fix.
If after reversing MS's first Duqu fix you still can't run sfc /scannow, research MS11-100 to find out if a 'duqu' fix was in there, or if it caused a denial of access to system files. If it did, sfc /scannow won't run. You can probably roll that one specific update back, but only do so when disconnected from the net.
Research that possibilty here: http://technet.microsoft.com/en-us/security/bulletin/ms11-100
However, reinstall it after you finish. It's that important.

I've had the same quirk for a couple of months regarding sfc /scannow. Isn't this the same scan and repair as the chkdsk option on the HDD? The one that starts on a reboot.

No. sfc /scannow deals with windows system files only and repairs any integrity violations.
chkdsk does only that. chkdsk /f /r scans for sector as well as file integrity, indexing, etc. repairs errors and is a 5 part scan (if i remember correctly) takes one helluva long time as well.

Hi Doc I downloaded the 2 Fixit msi files but haven't run them yet. I'll pull my wireless usb device out before doing that. I was wondering though after I ran chkdsk last night does it create a report anywhere telling me what it found?

Yo, BDBF. I'm really sure the problem came from that fix.
The logs should be in your cbs logs.

Well I found it Notepad can't open it. Access is denied. So what's the next hoop I have to jump through.

Not yet I was trying to read the CBS log. I had to copy it first and read the copy. The original is locked. It should stay that way. It was useless for me to try and read it.
I'll try the fix now offline.

Okay SFC /scannow ran and found some stuff to repair. Nothing changed though in any visible way. Ran the enable fixit went online and thanks at least I know now that to run SFC I will have to disable that access deny lock on the system font dll.

Worked here too. Thanks Doc!

I discovered another way to fix it that worked for me. I used the takecontrol.reg which I already had installed and took control of the system 32 folder. Now I can run sfc without issue.
Reply #39 Saturday, January 7, 2012 3:27 PM
JC, do you have the MS patch mentioned in #26 installed?
Reply #40 Saturday, January 7, 2012 3:54 PM
Yes Doc but even after I disabled it I still could not run sfc. Would only verify to 7%. Once I took ownership of my system files I ran and completed sfc. It found some corrupt files to.

Well I do remember MS had an emergency security update over the Holidays Framework too.
I'm thinking since the rapair tool can find no problems that just to be safe I can run a chkdsk over night its been 6 months since the last one.
