Since you said this is a Red Hat machine, I can point out a Red Hat 
specific tool.

/sbin/chkconfig 
Useful options are:
chkconfig --list shows which services are enabled at what level.
chkconfig <service> off   turns the services off.


Runlevels are a matter of debate between BSD-style and SysV-style systems. 
I always forget which is which and which one linux is, but one jumps 
straight from one level to the other and stops services that shouldn't be 
running and starts ones that aren't but should be. (This is linux)
The other starts in runlevel 0, and starts everything listed in runlevel 
1, then starts everything listed in runlevel 2, and then everything in 
runlevel 3, etc. So on this type of system, which I think HPUX is one, if 
you list something in runlevel 2 and in runlevel 3, it will be started 
twice.
