[Koha] koha accessible on the host machine only

I have successfully installed Koha 3 on Debian 5. I can access the koha page on the host computer by pointing to its Fully qualified hostname (http://koha.uz.ac.zw ), which is DNS-resolvable. However, on other computer on the intranet, if I point the browser to http://koha.uz.ac.zw, I am greeted with the Apache Page, " It is working". I am new to Debian but I have been using Redhat variants for some time. I will appreciate any hints to the problem Kind Regards, Admire Mutsikiwa (Mr) ICT Projects Manager Library IT University of Zimbabwe Tell:+263-4-303276 Cell:+263-92239187 Alt/email:amutsikiwa@gmail.com
