We are using Moodle as our chosen VLE for our college and have got to the stage of getting our students to log in. We chose to use phpBB as our forums (sorry, didn't like the moodle forums look and feel) and got our students to login during a lesson. The server groud to a halt as 50 students in two classes all tried to access the server. We beefed up the RAM to 4Gb and PhPBB works a treat.
During creation of courses in Moodle I found certain section paricularly adding teachers to courses brought IIS down with the 'service unavailable' error up. When I restart the service on the server it is fine.
We then moved on to Moodle expecting plain sailing and when students attempted to logon it brought IIS down and gave the 'service unavailable' error up. When we restart the service on the server Moodle is fine, until multiple logons are attempted.
We use LDAP authentication to minimise admistration of user accounts which works fine when you log on one at a time.
Any thoughts please?
