How the WFP feature works
The WFP feature provides protection for system files using two mechanisms. The first mechanism runs in the background. This protection is triggered after WFP receives a directory change notification for a file in a protected directory. After WFP receives this notification, 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.
If WFP finds the file in the cache folder or if the installation source is automatically located, WFP silently replaces the file. If WFP cannot automatically find the file in any of these locations, you receive one of the following messages, where file_name is the name of the file that was replaced and product is the Windows product you are using:
•
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Files that are required for Windows to run properly have been replaced by unrecognized versions.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 product CD-ROM now.

The network location from which these files should be copied, \\server\share, is not available. Contact your system administrator or insert product CD-ROM now.

You are probably just fine. I need to google more about the framework 3.0...
