Mac OS X Server 10.4 disables NetBoot and DHCP during upgrade

To re-enable the services, follow these steps:

1. Execute the following commands in Terminal. You will be prompted for your administrator password.
   
   

   cd /etc
   sudo cp -R xinetd.d ~/Desktop
   cd xinetd.d
   sudo rm *

2. Open the file /System/Library/LaunchDaemons/tftp.plist in your preferred text editor; for example, type this to open the file in pico:
   
   sudo pico /System/Library/LaunchDaemons/tftp.plist
    
3. Locate the following key and array:
   
   

           <key>ProgramArguments</key>
           <array>
                   <string>/usr/libexec/tftpd</string>
                   <string>-s</string>

4. In the second string shown above, change the -s value to -i.
5. Save the file and exit the text editor (in pico: press Control-O, Return, then Control-X).
6. Restart the server.
7. Keep the copy of the xinetd.d folder that you made on your desktop for backup purposes.
