Alright, I tried to do this but it didn't work. I have three drives and one is completely clear, so I figured I would just install OS X server 10.3 on 1 drive and have OS X client 10.5 on another drive. (I know that I am creating huge security holes when I would be running the server, but it would only be for a short time). When I set up the server, the hard drive with 10.5 on it would have no privileges except for admin. I would just switch the startup disks before rebooting between server or client. I go to do it, I pop the server disc in and reboot the computer and it just automatically goes back into 10.5. I tried to boot from cd but had no success. Mainly I am trying to use the server software to make a webserver for certain people to use Is this something that can be done through the sharing in system preferences in leopard?
