You are the network administrator for your company. The network consists of a single Active Directory
domain. All network servers run Windows Server 2003, and all client computers run Windows XP Professional.
Your company's main office is located in Dublin, which is also the location of all domain controllers. The Dublin office contains 200 client computers.
A branch office is located in Helsinki. This office contains 60 client computers. All user accounts for permanent employees in Helsinki are contained in an organizational unit (OU) named HelUsers. All user accounts for temporary employees in Helsinki are contained in an OU named TempUsers.
A temporary employee named Peter is hired in the Helsinki office. The business hours in his office are 9:00 A.M.
to 5:00 P.M. At 9:05 A.M. on his first Monday at work, Peter tries to log on to the domain from his client computer. However, he receives the message shown in the exhibit. (Click the Exhibit button.)

You need to ensure that Peter can log on to the domain.
