Hello the_fact,my answer is
coba liat disini ttg "scannow" http://www.updatexp.com/scannow-sfc.html
Well, in your computer's registry, are several settings that are checked when
you run scannow sfc.
As mentioned earlier in this article, the Windows File Protection service
constantly monitors for any changes to the main system files. Well Windows XP
keeps a cache (copy) of these essential files at the following location:
C:WINDOWS\System32\Dllcache (assuming C: is your system root which it probably
is.)
NB - The dllcache folder is extremely important so Windows XP hides it from
you! To view it go to: My Computer > Tools > Folder Options > View > "uncheck"
Hide protected operating system files.
If that's the case on your computer then there is normally no need for the
original XP CD to be inserted as your computer has a "copy" it can get hold of
in this cache...
But, if the Dllcache folder, or part of it, has become corrupted for some
reason then you will be prompted for the XP CD - so your computer can get a
clean copy!
Having said that not ALL installations of Windows XP have ALL the system files
cached into this folder! You may only have around 50MB of files in this folder
under Windows XP depending on the quota settings in the registry. (Under
Windows 2003 Server the default is 300MB of system files!)
Annoying, YES!
Is there a workaround YES!
As well as having a cache of all the system files on your PC, I like to have
the I386 folder from the XP CD installed on the computer as well. After doing
this I then modify the registry to tell it the source path for these files...
Why? Well not only does this prevent 99% of request for the the XP CD with
Windows File Protection. But the I386 folder also contains many other files
that are sometimes needed by the operating system and this stops those requests
for the XP CD too!
NB - With today's large hard drives you are not going to notice this 475 MB
folder on your computer, but older systems may not have the space for this...
Step 1
You will need to get your XP CD and locate the folder called:
I386
This is a major folder and should be one of the first you see, now copy this
onto your hard drive into the system root. For most of you that is going to be
C:\ so you should end up with a folder that looks like: C:\I386
-----------------------------
Step 2
Now you will need to tell your computer you now have the files on your PC. We
do this is the registry (type regedit in the Run box on the start menu) by
navigating to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup
You will see various entries here on the right hand side. The one we want is
called:
SourcePath
It probably has an entry pointing to your CD-ROM drive, and that is why it is
asking for the XP CD. All we need to do is change it to:
C:\
Simply double click the SourcePatch setting and a new box will pop up allowing
you to make the change.
Now restart your computer and try scannow sfc again!
------------------------------
Other Problems with scannow sfc...
#1
Has the CD Drive's drive letter changed (perhaps by the addition of another
hard drive, partition, or removable drive) since Windows XP was first
installed? If so, simply edit the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup\SourcePath to reflect the changed drive letter.
After you restart the computer, WFP and sfc /scannow uses the new source path
instead of prompting for the Windows XP installation CD-ROM
#2
Has the registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup\SourcePath got an incorrect entry? The SourcePath entry
does NOT include the path location till the I386 folder. It completes one
folder ahead to reach the I386 folder.
Example:
If the I386 directory is at C:\I386, the SourcePath value would be C:\
#3
If the problem persists and you have the correct path for your I386 folder then
the I386 folder is corrupted. To solve this problem copy I386 folder from the
CD-ROM to your system restart the system and then
perform sfc /scannow again.
#4
You do not have an XP retail CD with an I386 folder on it. If you have a
restore CD from your PC manufacturer then you may have to explore the CD to
find the folder.
#5
You still keep being prompted for the XP CD yet you have done all in this
article! There is another setting in the registry that may be causing the
problem. Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SourcePath
Make sure the entry here is the same path to the I386 folder as used above.
#6
Systems administrators can enforce security policies that may include changes
to the Windows File Protection settings. You will need to speak with your
network administrator about this, but it is important to bear in mind when
Windows starts up, the Windows File Protection service synchronizes (copies)
the WFP settings from the following registry key:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Windows File
Protection
to the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
Therefore, if any of the following values are present in the
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Windows File
Protection key, they will take precedence over the same values under the
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon key.
This will not effect scannow sfc so much, but WILL make an impact if any of the
other sfc.exe "switches" have been used! (More about these at the end of this
article.)
#7
When you run scannow at logon you do not get a progress bar... This can easily
be remedied by adding a new DWORD: SFCShowProgress to the registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon
the values available are: 0 = disabled, 1 = enabled
------------------------------------
What about Windows Updates.....
You may be asking yourself how does sfc.exe know how to check for updated
Windows system files? Well during OS upgrades, service pack installations etc..
the dllcache folder should be updated with these new files.
As an example the recent Windows XP Hotfix - KB828035 updated the system file
wkssvc.dll A new version of the file was placed in C:\WINDOWS\system32 and a
copy in the cache: C:\WINDOWS\system32\dllcache A copy of the old system file
is archived in: C:\WINDOWS\$NtUninstallKB828035$
There is another location the Windows File protection service uses and that is
the I386 folder in C:\WINDOWS\ServicePackFiles When you install a service
pack, like SP1. Any new system drivers are cached in this location too.
If you have odd problems with running scannow sfc and nothing else in the
article has resolved it, then take a look at the entry in:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Setup
\ServicePackSourcePath
This should be pointing to the location C:\WINDOWS\ServicePackFiles (assuming
C:\ is the boot drive.)
-------------------------------------------------------
For those of you who are familiar with sfc.exe under Windows 2000 professional.
It is worth noting that the following two options are NOT available under
Windows XP.
These are:
sfc /cancel - In Windows 2000, this command immediately cancels all pending
scans of protected system files. This option has no effect in Windows XP.
sfc /quiet - In Windows 2000 this sets Windows File Protection to replace any
incorrect system files detected with the appropriate version from the dll cache
without any user notification. This option has no effect in Windows XP.
so gak ada hubungane ama yg namanya "service" kan..??? gak make IMHO apalagi
bawa
golok ma sarung...
