Which release of RedHat are you running?  The 'ps' command behaves a little 
differently depending on which version you're running.  Older (5.x) 
releases generally use 'ps -aux', but newer (6.x and 7.x) versions use 
either '-ef' or '-aux'.  On my 6.2 box:

[esisler@gromit esisler]$ ps -ef | grep named
named      436     1  0 Feb11 ?        00:22:40 named -u named
esisler  17810 17298  0 08:14 pts/0    00:00:00 grep named

[esisler@gromit esisler]$ ps -aux | grep named
named      436  0.0  0.8  5932 3172 ?        S    Feb11  22:40 named -u named
esisler  17840  0.0  0.1  1212  460 pts/0    S    08:15   0:00 grep named

You can also try running nslookup on the box and see if it will resolve 
anything, assuming the box is configured to look at itself for resolution 
first.  If not, you'll need to specify the nameserver to use when you start 
nslookup.
