"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

go to Start -> Run, type MSCONFIG and click OK, click the button for Expand file.  Type in the name of the file  to replace in the File to Restore field, in the Restore From field, choose the option (probably the drive letter for your CD-ROM/DVD where you will place the WinXP installation CD), and type the name of the destination folder (Windows\System32) in the field for Save file in.  Then click the Expand button.

If that doesn't work, try the other methods from this MSKB article:

How to expand Windows XP files from the installation disk

Then reboot and see if the problem goes away.
