Disk Check WIndows File Protection Error

I was trying to free up more free space on the C DRIVE of my email server [HOU-EXCH2]. I RIGHT-CLICKED the C DRIVE and ran the DISK CLEANUP utility and ran the command to COMPRESS UNUSED FILES. The command ran until at the very end when a MENU POPPED UP that reads:

Windows File Protection
Files that are required for Windows to run properly have been replaced by unrecognized versions. To maintain system stability, Windows must restore the original versions of these files. Insert your WINDOWS SERVER 2003 CD-ROM now.

What would happen if I inserted the CD and ran the command? Did I completely blow up the operating system of our main EMAIL SERVER? What should I do?

THX

It appears that disk cleanup removed or compressed a file that Windows does need. You should most likely repair this file by following the instructions, but always make sure you have a backup before you do so.
I hope this helps. Good luck.

What if I do the following while the the "Windows File Protection
Files that are required..."  menu is still up:

Right click on C: drive. Click properties. Uncheck the box that says Compress files to save disk space or what not. Click Apply.

thx

Doing that should not affect anything, but you really should let windows fix the issue.

We went ahead and UNCHECKED the COMPRESS UNUSED FILES command on the DISK CLEANUP UTILITY. However, I didn't see any menu pop up showing the UN-COMPRESSION. Is this done in the background or does it require reboot? I have not rebooted the server yet.


thx

What would happen if we run this command on the server now:

Open a command prompt, go to the root of the hard disk, and type -> compact /u /s /a /q /I

Thx
