You can control access to non-NetBoot computers without having NetBoot clients by following these steps:
1. Install the NetBoot software and open the NetBoot Setup Assistant.- Reply Yes to configuring the server as a Macintosh Management Server.
- Provide valid IP numbers for NetBoot clients. It can be a range or one IP number.
- On the last screen of the Setup Assistant, click the Quit button (not the Restart button).
2. Select Computer Settings, Network from the Apple Menu.- Click the Connections tab.
- Select BootP from the Show pop-up menu.
- Click Global BootP to select it.
- Select Off in the Global Bootp Settings panel.
- Quit the Network applcation.
3. Restart your server for all changes to take effect.
If you decide later to add some NetBoot clients you can run the NetBoot Setup Assistant to configure it as a NetBoot server.
