You are upgrading a Windows NT Server computer named Server1 to Windows 2000 Server. Server1 is a BDC in the domain. The existing DNS server is a UNIX computer that supports SRV (service) records and is configured to accept dynamic updates. The existing WINS server is another Windows NT Server computer.
You want to configure Server1 as a domain controller in a New Active Directory forest. You want the existing Windows NT domain accounts to be upgraded to Active Directory. You plan to upgrade the other domain controllers in the domain to Windows 2000 after the upgrade of Server1 is complete.
You want to perform. the upgrade of Server1 with the least possible impact on other computers on the network. What should you do?
A．Promote Server1 to the PDC of the domain. Run Windows 2000 Setup on Server1.
B．Run Windows 2000 Setup on Server1. At the end of Setup, configure Server1 as a DNS server and a WINS server.
C．Add a static mapping for Server1 on the WINS server. On the DNS server, create an SRV record for the LDAP service on Server1. Run Windows 2000 Setup on Server1.
D．Install the Microsoft DNS service on an existing Windows NT server. Apply Windows NT 4.0 service pack 4 or later to the server. Run Windows 2000 Setup on Server1.
参考答案
正确答案：A
解析：Explanation: We want to upgrade the NT domain to an Active Directory domain; particularly we want to migrate the NT user accounts. First we need to promote server1 to PDC since it contains the master copy of domain information - SAM. Then upgrade the PDC to Windows 2000 Server. Active Directory requires a DNS server that supports SRV (service records). The UNIX DNS server supports this.
Incorrect answers:
B: Server1 must be upgraded to PDC before Windows 2000 is installed. Furthermore, there is already a DNS server on the network and Active Directory does not require a WINS server.
C: Server1 must be upgraded to PDC before Windows 2000 is installed. Furthermore, there is already a DNS server on the network and Active Directory does not require a WINS server.
D: Server1 must be upgraded to PDC before Windows 2000 is installed. Furthermore, there is already a DNS server on the network.
