Automounts are not working

[Dave Martini]

I have a RHEL 3 system and can't do automounts on it. I restarted the 
autofs service and I get this error.

# service autofs restart

My home directory doesn't ever get mounted or any other logical mount 
points that I CD to.

This used to work. Is there another service I should check or restart or 
is autofs solely responsible for automounting file systems?

Thank You
