Setting Up and Managing User Accounts
4. Which of the following statements about deleting local groups are correct (Choose all that apply.) a. Each group that you create has a unique identifier that cannot be reused. b. You can restore access to resources by re-creating the group. c. When you delete a group, you also remove the permissions and rights associated with it. d. Deleting a group deletes the user accounts that are members of the group.
The correct answers are A and C. B is not correct because re-creating a group does not re-create the membership of that group or any of the rights or permissions associated with that group. D is not correct because deleting a group does not delete the user accounts that are members of the group. Deleting a group does remove any rights and permissions that were extended to the members of the group by virtue of their membership.
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 examples of each type of group.
Built-in local groups give rights to perform system tasks on a single computer, such as backing up and restoring files, changing the system time, and administering system resources. Some examples of built-in local groups are Administrators, Backup Operators, Guests, Power Users, Replicator, and Users. Built-in system groups do not have specific memberships that you can modify, but they can represent different users at different times, depending on how a user gains access to a computer or resource. You do not see system groups when you administer groups, but they are available for use when you assign rights and permissions to resources. Some examples of built-in system groups are Everyone, Authenticated Users, Creator Owner, Network, Interactive, Anonymous Logon, and Dialup.
Case Scenario Exercise
Page 7-46
1. Your first task is to create a naming convention for these workers. The museum management would like the user names to reflect that these are temporary workers, but not require too complicated a user name for the workers to type. Use the following table to create names for the workers.
Full Name Cat Francis David Jaffe Mary North Jeff Teper Bernhard Tham User Account Name
Questions and Answers
7-57
There are a number of ways you could create these user names. One way would be to use the first initial and last name of each person to create the user name and then to prepend each user name with a T to indicate the workers temporary status. This could give you the following user names:
T_cfrancis T_djaffe T_mnorth T_jteper T_btham
2. Where should you create these user names
You must create a local user name for each user on the user s workstation. You must also create a local user name for each user on the file server so that you can assign permissions.
3. The file server in the workgroup contains a folder named Coal Research, to which each of the workers needs access. You would like to minimize the number of times you have to assign permissions to the Research folder. How would you do this
You should create a local group on the file server. You should name the group something simple like Coal Researchers and then add each of the workers user names to that group. You can then assign permissions to the group for the Coal Research folder rather than assigning permissions to each user name.
4. When creating passwords for the users on their workstations, what must you ensure so that the users can access the file server
You must not create blank passwords for the users on their workstations. Although blank passwords would allow the users to log on to their workstations and access local resources, the default security configuration on the file server is to enable the Accounts: Limit Local Account Use Of Blank Passwords To Console Logon Only security setting, which would prevent users with blank passwords from being able to access resources on the file server remotely.
