This is not a missing font. It is another component of your installation.
What OS version?
Is it InDesign CS2?
How did you install it on your computer?
You need to reinstall the application. Somehow this file (not a font file itself) required by InDesign was deleted off your system or got corrupted. This might be indicative that other parts of your InDesign installation may also be corrupted. Uninstall and reinstall.
