OK, from what I can decypher you're running RHEL4u4 and RHEL5.3.  These use 
different software update systems.

RHEL4 - up2date
RHEL5 - yum

Neither are 'automatic' unless you set up a cron job to have them install 
updates (although I think you can get RHN to auto-push, I can't remember). 
For all versions of RHEL you need to ensure that you have a valid and 
current subscription to Red Hat Network to get access to updates.  This is 
something you would have paid for.  If you don't want to pay money I would 
recommend switching to using CentOS as your operating system.  CentOS is 
essentially a free version of RHEL.  This would require reinstalling your 
machines as the easiest way to achieve this given my assumption of your 
level of knowledge.  Explaining how to get a subscription to RHN is outside 
the scope of this email.  However, if you have one, registering your machine 
with RHN is something we can work through.  YOU MUST HAVE A VALID PAID-FOR 
SUBSCRIPTION BEFORFE TRYING TO USE RED HAT NETWORK.

If you have a valid subscription to RHN, and installed your RHEL operating 
system from an authorised RH source, the correct base repository (not 
depository) should already be set up for you.

For RHEL4 simply run the command "up2date".  For RHEL5 the command is "yum". 
Both have extensive man pages both on your OS and on the web.  Using them is 
very straightforward.

Have fun.
