[单选题]You are the administrator of a network that includes Windows NT Server 4.0 computers, Windows NT Workstation 4.0 computers, and UNIX computers. The network consists of a single Windows NT domain.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.

正确答案 ：C

Promote Server1 to the PDC of the domain. Run Windows 2000 Setup on Server1.

解析：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.

[单选题]You are the administrator of your company's network. A user named Paul in the service department has a Windows 2000 Professional computer. Paul needs to access the files that are in a shared folder on his computer. A local group named Sales has permissions to access the data. Paul is a member of the Sales local group but he cannot access the file he needs.What should you do?

正确答案 ：C

Remove Paul from any other group that has been explicitly denied access to the Sales folder.

解析：解析：Explanation: The Sales group, which Paul is a member of, has permission to access the files. However, Paul still cannot access the files. It would seem that Paul has a permissions conflict. A user can be granted file permissions in a number of contexts: as a user or as a member of a user group. When a user has different file permissions in multiple contexts, the most restrictive permission is applied. Furthermore, the deny permission overrides all other permissions. As Paul does not have access to the file you must therefore assume Paul has explicitly been denied access to the file in some context, as member of one or more groups that have been denied access to the file. You would thus have to remove Paul from such a group so that the restriction is not applied to Paul.
