5. What is the difference between built-in system groups and built-in local groups
found on computers running Windows XP Professional? Give at least two exam-
ples of each type of group.
Lesson Summary
■ Groups simplify administration by allowing you to assign permissions and rights
to a group of users rather than to individual user accounts. Permissions control
what users can do with a resource such as a folder, file, or printer. Rights allow
users to perform system tasks, such as changing the time on a computer and back-
ing up or restoring files.
■ Windows XP Professional creates local groups in the local security database, so
you can use local groups only on the computer on which you create them.
■ You can use the Computer Management snap-in to create, add members to, and
delete local groups.
■ All computers running Windows XP Professional have built-in local groups that
give rights to perform system tasks on a single computer.
■ Computers running Windows XP Professional also have built-in system groups
whose membership is determined dynamically.
Case Scenario Exercise
In this exercise, you will read a scenario about creating users and groups and then
answer the questions that follow. If you have difficulty completing this work, review
the material in this chapter before beginning the next chapter. You can find answers to
these questions in the “Questions and Answers” section at the end of this chapter.
Scenario
You are an administrator working for the Baldwin Museum of Science. The museum
has hired a number of temporary workers that will be researching information for a
new exhibit on the history of coal use in northern Europe. Each of these workers has
been assigned a workstation in a small workgroup that the museum has set up in the
exhibit room. One computer in the workgroup is acting as a file server where the
workers will store their research files. All workstations and the file server are running
Windows XP Professional.
The temporary researchers’ names are as follows:
■ Cat Francis
■ David Jaffe
■ Mary North
■ Jeff Teper
■ Bernhard Tham
