RE: Error at 473 in /var/www/html/vcl/.ht-inc/computers.php
Andy, Many thanks for all your support. I figured that i disturbed the database by editing some fields via phpMyAdmin and therefore ended up deleting the VCL database and starting from scratch by recreating and importing the default vcl.sql db. I then fixed the DHCP on the public interface, recreated the base image and it all worked like a charm.

Re: Error at 473 in /var/www/html/vcl/.ht-inc/computers.php
This looks like it may be a problem in the database. The line in computers.php where error is occurring is attempting to print out the name of the current image loaded on the computer. The ID of the image is 4 -- which should be the noimage image: Unkown error type: [8] Undefined index: 4 By chance delete the noimage image from the database? If so, you'll need to add it back. If not, please include the output from: SELECT * FROM computer SELECT * FROM image SELECT * FROM imagerevision Regards, Andy On Mon, Sep 12, 2011 at 2:25 PM, Jeries, Ibrahim (Student) ibrahim.jeri...@student.anglia.ac.uk wrote: Dear all, Can anyone help with following issue?
