There are four installation options available to a user of the Client Installation Wizard on the setup options screen (Choice.osc). They are:
A user's available installation options are determined by RIS Group Policy settings in conjunction with the user's specific security group or user account. For example, you might choose to provide all members of the Help desk security group with access to all of the installation options, but restrict general network users to only the Automatic Setup and Maintenance and Troubleshooting options. This prevents confusion and helps to guide users to the correct choices for operating system installation.
This option provides the easiest operating system installation path. If there is already a computer account object in Active Directory with a GUID that matches the client's GUID, the client is named the same as the existing computer account, and the existing computer account is reused. If a matching GUID is not found in Active Directory, the client is named based on the automatic naming format configured in the properties of the RIS server, and a new computer account is created in the location specified by the RIS server. For more information about changing the automatic naming format or the location in which to create automatic computer accounts, see "Configuring RIS Servers" earlier in this chapter.
This option allows users to override the automatic computer naming process, as well as the default location within Active Directory where client computer account objects are created. Because the default installation of RIS is configured to generate computer names based on which user logs on to the client, it is not appropriate to use the Automatic Setup option for setting up another user's computer. The Custom Setup option is similar to the automatic option, but it gives you the ability to set up a client for other users. For example, Help desk personnel can use this option to preinstall an operating system on a client within the enterprise, prior to delivery to the user. If either the computer name or computer location box is left blank on the Custom Setup screen, then the automatic name or location is used.
Warning
If the name and location entered in the Custom Setup screen and the GUID of the client match the name, location, and GUID of an existing computer account object, the existing computer account object is reused. If only one of the fields between GUID, name, and location match, a duplicate name or duplicate GUID error screen is presented. However, because the user can bypass the error screen, do not use the Custom Setup option when you are creating prestaged computer accounts for use in installations performed directly by users.
If the installation process fails or network connectivity is disrupted during the initial text-mode portion of setup (prior to completion of the file copy stage), a Restart Setup command is available for optional display to the user the next time the computer is started.
If this option is selected, it restarts the operating system installation process by using the information entered during the previous attempt. This option is controlled by the existence of the client-specific temporary answer file generated by RIS, which is deleted prior to running the graphical user interface portion of setup.
This option provides access to maintenance and troubleshooting tools, such as system flash BIOS updates and computer diagnostic tools, that can be used prior to operating system installation.
