Configuring Network Boot Service for unknown computers
After an unknown computer is added to a network, you must boot the computer in the preboot environment. To boot computers in the preboot environment, you must install the Network Boot Service (NBS) on a site server and configure the site server with the NBS settings for unknown computers.
To configure site server with NBS settings for unknown computers
In the Symantec Management Console, click Settings >Deployment > NBS General Settings.
In the NBS General Settings dialog box, for the Network Boot Service Configuration, configure the settings for the unknown client computers.
Network Boot Service Configuration
Lets you configure the Network Boot Service (NBS) for a site server.
To enable or disable the policy, you must select the Turn On or Turn Off icons on the right side of the dialog box or page.
Apply NBS settings immediately
Check the option if you want to apply the NBS policy immediately on the site servers.
If the option remains unchecked then the NBS configurations changes are applied as per the schedule set in the Symantec Management Agent (SMA) for rolling out policies.
Enable the NBS service
Check the NBS service to enable the service on the site server.
By default, this option is checked.
Lets you restore the previous configuration that you performed for the NBS site server.
In the NBS General Settings dialog box, for the PXE menu (Windows/Linux) tab of the Initial Deployment (Unknown Computer) Menu, specify the following:
Lets you select the PXE image to deploy on a Windows or Linux client computer.
The fields for the tab are as follows:
Respond to unknown computers
Check this option if you want to respond to the unknown computers to configure them to boot in the preboot environment using a PXE image.
PXE boot image
Select the PXE image that you want to use to boot the unknown client computers in the preboot or automation environment.If you do not want to boot using a PXE image, you can select, Next Device (BIOS/EFI) mode of booting option for the client computer. Based on whether the default boot option of the client computer is set to BIOS or EFI, the computer boots to the preboot environment. The potential boot devices of BIOS are CD, disk, and so on. Computers of UEFI architecture can boot in the preboot environment using the x64-bit PXE image of Windows.
For the PXE image, select any of the following architectures from the drop-down list:
Select this option if you want to boot the client computer based on the computer's processor architecture. For example, if you have a client computer whose processor type is x64 but the installed operating system is x86 of Windows 7, then the Auto option boots the computer in x64 architecture mode and not in x86 mode.
The Auto option can be useful if you have created a common PXE image for both x86 and x64 architectures or want to boot a computer as per the processor architecture irrespective of the OS architecture. You create PXE images through the Create Preboot Configuration dialog box of the console.
Select this option if the PXE image that you have created is for the x86 architecture of the operating system.
Select this option if the PXE image that you have created is for the x64 architecture of the operating system.
Configure the schedule of the network boot menu through the following:
Run default boot option immediately
Select this option if you want to deploy the PXE boot image immediately after you select the image in the drop-down list.
Wait indefinitely for user selection
Select this option if you want to manually select and deploy the PXE boot image from the network boot menu. The network boot menu appears on the unknown computer.
Run default boot option after
Select this option if you want to deploy the PXE boot image after the time period that you specify in the text box. After the time out, the client computer boots to the PXE image that you have selected. Press F8 to invoke the network boot menu to deploy the PXE boot image on the client computer.
Click Save changes.
Again, in the console, click the Settings >Deployment > NBS Global Settings menu.
