You have to issue condor_restart from a machine listed in  
HOSTALLOW_ADMINISTRATOR in the config file. By default, only the  
central manager is included. Since anyone on listed machine can issue  
these commands, you want limit the list to machines with restricted  
logins (or set up strong, user-based authentication). You can also  
just kill and restart the master.

Your change to DAEMON_LIST should prevent the schedd from being  
started, but the master won't automatically stop an already-running  
schedd. If the schedd is still being started when you restart the  
master, run 'condor_config_val -v DAEMON_LIST' on the machine. That  
will tell you what value of DAEMON_LIST is being used and where it's  
being defined.
