problem with mount -t smbfs

[Gregory Leblanc]

This was working a couple of weeks ago, but it's broken now.  When I issue a
command like 'mount -t smbfs //server/share /mount/point' I get an error
that says "
mount: wrong fs type, bad option, bad superblock on //mrbig/grego$,
       or too many mounted file systems
"

However, when I issue the command 'smbmount //server/share /mount/point/ it
works just fine.  I've been unable to figure out what's going wrong.  Any
hints?
