View Full Version : sfc /scannow wont run?

29-03-2006, 09:49 AM
I’ve got a mates computer that pulls up an Error 1933 message whilst trying to install Office.

One of the suggestions from the MS site is to run sfc /scannow.

Fine, except I can’t get it to run? All I get is what looks like a DOS screen flash across and we return to the desktop.

Anyone any suggestions?

XP Home Service Pack 2 (build 2600)

Everything else seems to run fine.

You may get a better idea of why its not running if you do it from a cmd box.

Start -> Run then type in cmd and hit ok - in the box that appears type your sfc /scannow

Yep, but now I’m really bushed. Here’ the message.

Specific error code is 0x000006ba
The RPC Server is unavailable. :help:

from the same box type net start rpcss

Has some one been shutting down the default services on this machine, perhaps to make it more secure or run faster ?

Ok, new message: The requested service has already been started.

More Help ........... etc.

Thanks for your time graham.

About now I'd be thinking about doing a complete reinstall of the OS, might be quicker than trying to repair this hosed OS.

Right, I’m thinking along those lines too.

However, how do I go about that without having to download and reinstall all the service packs and updates?

The annoying part is everything seems to work perfectly except I can’t install Office 2000 and can’t run sfc.exe.

Is there some way to do an over the top reinstallation with XP? I have done with Win98 SE but am not familiar with XP.

Check out


but don't forget to backup the data you want to keep before doing any of this.

Thanks Graham. I'll let you know how I get on. :thumbs:

just run a repair install instead of a 'clean' install that should cure any operating system faults.......boot from xp cd then go thru th eprocess as if you are gonna install ......it should give you the option of 'repairing' the existign installation......do that...you wont lose any data/ or anything.

But sfc /scannow is supposed to "cure any operating system faults.......". :groan: :help: :badpc:

UM........NOT as effective as a repair install

Just to let those that helped know what the outcome of this saga.

Surprise, surprise, the mate couldn’t find his XP disk initially. :blush:

So, I rolled back to the first restore point.

Then another surprise, sfc /scannow worked, and an even bigger surprise, it didn’t find any corrupted files.

I then cleaned out all the c..p and Office installed no problem.

Oh, and wouldn’t you know it, having finished the mate turns up with his XP disk! :D

My only regret is I didn’t get a chance to try an “over the top” install to see how it went or if I could. No doubt my chance will come. ;)

So thanks again everyone. :)
