|  | Planning an Installation of Microsoft Windows XP Professional Deciding on a Workgroup or Domain Installation
Workgroup vs. Domain Typically, the Network Administrator or Network Architect decides whether to install Windows XP Professional in a workgroup or domain. If the Network Administrator or Network Architect does not make the decision, the Windows XP Professional Pre-Installation Checklist, located in Appendix A on the Student Materials compact disc, can help you decide whether to install Windows XP Professional in a workgroup or domain. However, if you review the checklist and are still unsure, join a workgroup, because you can join the domain after completing the installation.
