You work as the help desk support technician at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com.
A user named Andy Booth reports that after upgrading his computer from Windows 98 to Windows XP Home Edition, he is unable to log on to the domain from the welcome screen.
You must make sure that Andy Booth is able to log on to the domain.
Which of the following is a task that you should instruct Andy Booth to execute?

A.
To log on as an administrator and change the workgroup name to the name of the domain in System in Control Panel.

B.
To run the Network Setup Wizard.

C.
To clear the Use the Welcome Screen check box in User Accounts in Control Panel.

D.
To upgrade to Windows XP Professional and join his computer to the domain.

Explanation:
Microsoft has crippled the Home version of Windows XP and made it impossible to join it to domains and in that way forced the majority of companies to invest in the slightly more expensive Windows XP Pro.
