Remote Installation Errors

I have set up my DHCP, DNS and installed and configured my Remote Installation Server. Everytime I go to the client machine and try to boot to the network, I get the DHCP to assign my IP, I get to the point where the program is formatting the client harddrive and I get an error for not enough memory or the installation files are corrupt. I have tried 4 different copies of Windows 2000 Professional and I haven’t gotten it to work. Same error, different install. Please help, Thanks, Jeremy
