Chapter 4. Panel-Driven Installation

4.1 Introduction

Even if you plan to migrate your servers using the unattended technique, we recommend that you execute a panel-driven installation to get the feeling of what is going on during this process. So, in order to help you as much as we can, we will try to highlight some valuable points when preparing a CID installation.

To clarify terms in this chapter, we will differentiate three types of servers:

Primary Domain Controller (PDC)

Responsible for validating user logons and maintaining logon assignments

Backup Domain Controller (BDC)

Keeps a read-only copy of the users information and is able to take over the function of the PDC when the PDC is down or just overloaded

Additional Servers

Hold the users private and shared files, applications, and control the various print queues

We assume that the PDC and BDC do not hold any user related files that are related to the File and Applications servers. That is, we will certainly find Access Control Lists (ACLs) on these, which will probably have the 386 HPFS file system installed, while the PDC and BDC can just use HPFS or even FAT.

In your organization, with your network configuration, the actual servers may play two of these roles. We will assume these functions are on separate servers, but you can logically add the items related to the role actually taken by a given machine to have a good idea of what is to be done during the preparation and the validation of your migration. Obviously, the installation of the new system, by itself, will be the same in all cases, and we will describe it only once.

We will mention some tools we used during our tests. These tools are on the CD-ROM accompanying this redbook. For simplicity, we have put brief information about these tools at the end of this chapter.
