XP asking for Windows XP Professional CD occasionally.

[casv]

Hi all.

I am using Windows XP professional. Everything was OK with
the exception of an error that pops up occasionally,
asking to insert a Windows XP professional CD, something
like your code is not accurate and may caused system
problem. After I inserted the XP’s CD media, it looks OK,
but after several days, it pops up the same error again.

Please advise.

Hi,

Windows XP supports Windows File Protection (WFP), which prevents programs
from replacing critical Windows system files. Programs must not overwrite
these files because they are used by the operating system and by other
programs. Protecting these files prevents problems with programs and the
operating system.

WFP determines which file was changed. If the file is protected, WFP looks
up the file signature in a catalog file to determine if the new file is the
correct version. If the file is not the correct version, WFP replaces the
new file with the file from the cache folder (if it is in the cache folder)
or from the installation source. WFP searches for the correct file in the
following locations, in this order:
1.. The cache folder (by default, %systemroot%\system32\dllcache).
2.. The network install path, if the system was installed using network
install.
3.. The Windows CD-ROM, if the system was installed from CD-ROM.
It's the 3rd option which asks you insert the XP CD-ROM to restore the
corrupt system files.

something is changing protected windows files.

1 update virus definitions and run a full scan
2 use start run msconfig and turn off third party
programs by unchecking load startup items if the issue
goes away then one of your third party programs is
updating over the internet and replacing windows files.

which means you open msconfig and startup top right and
start checking programs and ok and reboot till you get
problem back(note each test must be two or more days long
to validate the results)
