You are installing Windows 2000 Professional on a standalone computer that is not currently connected to any network. During Setup, you are prompted with the option to make this computer a member of either a domain or another type of logical grouping. In this non networked scenario, what should you specify that this computer is a member of?

Introduction / Context:
This question addresses basic networking concepts in Windows 2000 Professional Setup. Even when a computer is not part of a domain, Windows allows it to be associated with a workgroup name. Understanding the difference between domains and workgroups is fundamental for deploying Windows clients in both standalone and networked environments.

Given Data / Assumptions:

• The computer is not connected to any network during installation.
• No domain controllers or Active Directory infrastructure are available.
• Windows 2000 Setup prompts you to choose domain membership or an alternative.
• The user still wants to complete Setup correctly.

Concept / Approach:
Domains are centrally managed collections of computers and users, requiring at least one domain controller and network connectivity. Workgroups, by contrast, are simple peer to peer groupings used primarily for organising computers in smaller or non domain environments. When no domain is available, the correct choice is to specify a workgroup name. This allows the system to operate as a standalone machine and later join a domain if needed once connectivity and domain services are available.

Step-by-Step Solution:
Step 1: Recognise that domain membership requires a domain controller and network connectivity.Step 2: Note that the scenario explicitly states that the computer is not on a network.Step 3: Understand that in such scenarios Windows 2000 Professional should be configured as part of a workgroup.Step 4: Choose the option that states the computer should be a member of a workgroup.

Verification / Alternative check:
Windows documentation explains that standalone installations typically use the default workgroup name, such as WORKGROUP, and can later join a domain if administrators provide the required credentials and connectivity. Attempting to join a domain during Setup without connectivity will fail, leading to unnecessary troubleshooting.

Why Other Options Are Wrong:
Option a and option b propose joining a domain when no domain is reachable, which is impossible during Setup. Option c mentions an email group, which is unrelated to Windows logon and network grouping. Option e claims no membership is required, ignoring that Windows expects a workgroup or domain name to be defined even in simple scenarios.

Common Pitfalls:
New administrators sometimes try to pre create domain membership during Setup on isolated machines, leading to confusion when authentication fails. Others ignore the workgroup option and leave settings inconsistently named across machines. Using a simple workgroup name for standalone computers keeps configurations tidy and allows an easy transition to domain membership later.

Final Answer:
You should specify that the computer is a member of a workgroup, which is appropriate for a Windows 2000 Professional system that is not on a network.
