scannow prompts for disk but I'm sure it has correct disk

Intel Dual Core 2.4Ghz / XP MCE SP2.

Running sfc /scannow I get the following message that is well documented on this forum and elsewhere: "Files that are required for Windows to run properly must be copied to the DLL Cache. Insert your Windows XP Professional SP2 CD-ROM now."

My problem is that I know I am using the correct CD, and I can't see why Slipstreaming should be necessary, but I still get the error.
Some history:

01 New PC supplied from manufacturer with XP MCE SP2 backup disk
02 Reformatted the HDDs and rebuilt the PC how I wanted it to be using this backup disk to load the o/s
03 After installing a particular application I started to get odd behaviour so ran sfc /scannow
04 The error reported above occurred so I checked that the CD has a full i386 directory (it does, of course given I used it to build the PC)
05 Copied the i386 directory from CD to become C:\i386
06 Edited the famous SourcePath and ServicePackSourcePath registry entries to C:\ instead of my master CD/DVD read writer M:\
07 Rebooted
08 Observed that scannow got further than before (looking at progress bar) but still eventually fails as reported
09 Tried moving i386 to c:\windows\i386, changing the registry settings, and rebooting, but same problem
10 Found reference to disabling the Group Security Policy for "Restrict CD-ROM access to locally logged-on user" but mine was already disabled


So, three questions, please:

1) Why does the error refer to a XP Pro SP2 disk when I am running XP MCE SP2?
2) How can scannow fail with this error when I know it is being pointed at the correct source i386 directory and I know it is using it?
3) Could a Windows Update have loaded a file that is not on the SP2 disk?

Very Grateful thanks; my head hurts, my eyes hurt, it's 03:24am here in the UK, and I'm going to bed with an unsolved software problem (I hate "defeat" Wink

The C:\i386 has an error (SP2)

In reply to: scannow prompts for disk but I'm sure it has correct disk

Also, it is Windows\ServicePackFiles\i386, you may be better off installing SP2 from www.windowsupdate.com.

Downloading SP2

>>Also, it is Windows\ServicePackFiles\i386

Thanks, but surely it matter not where I put i386, so long as the two registry entries point to it? I thought I had proven this already.


>>you may be better off installing SP2 from www.windowsupdate.com.

I tried to do this, but the website won't let me download SP2 because it is installed already. When I browsed the rest of Microsoft.com to find SP2 in a "downloadable" state, downloaded it, extracted the i386 folder, and performed scannow, a) I *still* got the reported error message and b) it also screwed up my network card (find it hard to believe NetGear would mess with Windows core files) and I had to revert to an old save point.

In reply to: scannow prompts for disk but I'm sure it has correct disk

hi think the problem might be the disc your using. you need to have an original certified windows xp mce sp2 disc not a backup/recovery disc

one problem is microsoft only distributes these discs to MSDN subscribers and OEM system builders not any retail outlets

also mce is more or less xp pro with added extras and its the only version of xp to come with media centre software preinstalled

also have you tried a repair install

hope this helps dan

Scannow

In reply to: scannow prompts for disk but I'm sure it has correct disk

So the fact that I was able to completely rebuild my PC from the ground up (reformat both HDDs, install XP MCE SP2 from the backup disc, install motherboard drivers from the supplied motherboard disc) doesn't imply that I have an original certified windows XP MCE SP2 disc? If so, I have just learned something for which I thank you, but am amazed; surely the majority of PCs come either preloaded with XP, some with a "backup disc" like mine, implying scannow can't work on the majority of machines?

>>also have you tried a repair install

No! Why not? Having read some horror stories, fear! I have a PC that works beautifully but on which scannow fails. As a matter of principle I want scannow to work (even though the dodgy software problem that prompted this thread is now solved) but not at the risk of breaking anything! I have been married to this machine more than my wife in the last week, and another few late nights / early mornings would go down like a lead Zeppelin! Wink

Thanks anyway!

hope this helps dan
