SFC fails to scan on XP Pro with SP2

[Chris]

hi,
not long ago I upgraded my Win XP Pro from SP1 to SP2. There were some file
protection problems which needed to be repaired, so I decided to try running
SFC /scannow from a run box figuring I could use the original SP1 CD in
order to do the scan. I didn't think about there being a conflict with SP2 .
I keep getting prompted for the XP CD - which is put in cd rom drive.

When I press more info I see reasons listed for why the scan is halting,
they are either the CD drive isn't working, or an incorrect version of
Windows XP is installed. How do I fix this problem so I can perform this
scan without the CD. Didn't M$ upgrade system file checker for SP2 as part
of update?

With SP2 installed there ought to be a folder
C:\Windows\ServicePackFfiles containing the files to use in such
circumstances, and a reference to it in registry -
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Setup
and in The right pane ServicePackSourcePath set with that folder as its
data

Along with ServicePackFiles value, you need to modify the key above
it called CDInstall and set the value to 0.
This tells XP that source media is either on a disk drive (local or Network)
and that a CD-ROM isn't required.
The search path for source files is usually:
(1.) DllCache [SFC /Scannow re-populates this folder]
(2.) ServicePackFiles
(3.) i386 (Original, used to install XP)

Thanks everyone for your help... I wondered about the CDinstall modification
in Registry... I also made a 'Slipstreamed disk' for SP-2 as well, so I
should be good to go. Again thanks.

But then you are going to have to copy the original CD to HD (in
principle just the files not in the SP - but life's short) . With it at
1 you should be able to have the CD in the drive as fall back if a file
is not found in the search you describe. 1 is the standard setting left
after installing SP2.

SP2 also introduces a Service Pack Cache Files folder - I don't know
what function that has
