How can you tell system files were overwritten or corrupted?

That is the $64,000 question! ;-)
If you get error messages telling you that dll's are missing you might want to run the command. If you are having problems and if Windows or Internet Explorer are not running properly you might want to run the command.

Sfc /scannow
John,
You're absolutely right: $64K question. Life is so much depending on computer, it is nice to know how to trouble shoot when problem starts. There are all sort of problems associated with computers. The problem could be caused by software, hardware, or overwriting system files. To laymen, if we know the situation when we could fix certain problems simply by running sfc/ scannow, that could save time and money before bringing computers to shop. That is my question.

It's the kind of thing where you go through troubleshooting steps and as
you progress along if nothing seems to fix the problem you then move up the scale of possible fixes. If you are at the point in the troubleshooting and repair efforts where you think that you need to send the machine to a repair shop then you could certainly try running SFC, it won't hurt anything to try it! If running SFC doesn't fix things then you have to move up the scale of fixes again, at that point maybe a System Restore can fix things or maybe your options are getting scarce and you may have to resort to a repair install. There is no cut and dry answer to your question, all I can say is start with the obvious easy suggested fixes to the problem at hand, if the easy fixes don't work then try the more elaborate (or less palatable) fixes.

What you said here makes a lot sense.
How about check with repair? What does that fix? Roman "John John" wrote in message ...

Before you move on regarding System File Checker. A lot of problems resolve down to problematic drivers or memory. Where this is the case you often do not know which it is so you work through the easier solutions. If your Window XP CD contains the SP2 update using System File Checker is an easy task. It's not easy if your original Windows XP CD is pre SP2 as you need a slipstreamed CD to run System File Checker. A slipstreamed CD is a CD where the contents of the original XP CD and the SP2 update have been merged. -- Hope this helps.

Hi Gerry;
If you don't have a slipstreamed cd or if you don't have one at all (you only have a service partition or a "restoration" cd) you can just change the "SourcePath" in the registry and change the location of files so that SFC will look in the i386 folder instead of the cd. http://www.pchomecall.org.uk/support/sfc.htm Regards; John Gerry wrote: Roman Before you move on regarding System File Checker.

I take your point. Nevertheless just inserting a single CD is much simpler than point it to a folder when the user may not be sure where it is. The link you provided would appear to have been written before the SP2 update. The path for the i386 folder on this machine is different to that described in the Article. It is C:\windows\ServicePackFiles\i386. Thanks for reminding me of i386. -- Regards.

John,
Since I did not have a slipstreamed SP2 CD, I did not try sfc /scannow when I had problems with HDs two weeks ago. Upon reading your post, I made a slipstreamed CD yesterday by following Paul Thurrott's instruction. I also created slipstreamed SP2 CD for my Dell computer (for home use). Thanks again for the suggestion about slipstream. Regards, Roman "John John" wrote in message ...

You're welcome. It's a very good idea to have a CD with the same
Service Pack, if you ever need to do a repair install you will need it anyway, so it's best to be prepared. One less hassle to deal with when disaster strikes!

John,
I have a related question for you. A minor problem started when I started to make SlipStream SP2 disks We have two Dell computers at home ( for my self and wife). Mine is XP Pro SP1 and my wife, XP Pro SP1a. While copying the XP Pro SP1 disk to a hard drive (at c:\xp\i386), one file could not be read. That was I386\LANG\SIMSUN.TT_ (5,321,389). What I did was that I copied the same file from my Wife's XP SP1a disk and pasted to c:\xp\i386. The file size was the same between two XP disks but the date was different. Then, SP2 was integrated without any hitch. I wonder whether the replacement of the Simsun.tt_ from a different XP would matter when I use the slipstreamed disk for sfc/ scannow or reinstalling windows? (I feel that the original XP SP1 probably cannot be used for installing windows because of the corrupted file). Regards, Roman "John John" wrote in message ... You're welcome.
