[CentOS] rexec error - where are you

Hi all,

I've a particular host on my network that when I run;

rexec -l username -p password remotehost command

it just hangs.

When I do;

rexec -a -l username -p password remotehost command

i get; Where are you?

If I do;

rexec -l username -p password localhostname (not just localhost but  
its actual name) command

it works.

Any ideas would be very appreciated.
