I have ubuntu 12.04 (original) installed on a server.

How do I upgrade this to 12.04.03?

To upgrade an ubuntu system type in the terminal:

sudo apt-get update

...to update the package list.

sudo apt-get dist-upgrade

...to install all new versions of the installed applications and handle changing dependencies.

You should then see this:

user@host:~# cat /etc/os-release | grep VERSION=
VERSION="12.04.3 LTS, Precise Pangolin"

Note that you should probably use the (slightly misleading named) command dist-upgrade instead of upgrade here, since upgrade only upgrades existing packages, but doesn't handle any dependencies that may have changed. See askubuntu.com/questions/81585/… –  chronitis Nov 6 '13 at 10:28
