Question about fonts?

[bfischer at usgs.gov]

I am very new to the mapserver and am starting to play around with things.
I ran into a problem with the fonts.  I am using the NT version of
Mapserver running under Windows NT IIS.  This is the error I get from the
mapserv.exe:

msGetLabelSize(): TrueType Font error. Requested font (arial) not found

I figure I don't have the fonts set  or put where they need to be.  Here is
the map file I am using.
