I have a new G3/450 server set up to allow net booting. I have a few test stations set up to try it out. My rev. A iMac works fine and net boots, but I tried a new G3/400 and it won't net boot. I checked the firmware and it's the latest version. What gives?

I found the answer to my problem in case someone else runs into the same one. I searched through Apple's Tech Infor library and found out that when a machine boots from an OS X Server, the server grabs that clients ethernet port address and keeps that number in a database and assigns an IP adrress to that computer. Once the client computer shuts down, the server doesn't recycle that IP address. We only had two IP addresses reserved for netbooting, so they had been all used up and that's why I couldn't netboot.
