正确配置ip地址以排错
原题：
you are the network administrator for pcjob. the network consists of an active directory domain named pcjob.com. the domain contains computers running windows 2000 server, windows 2000 professional, and windows nt server 4.0. for the 10.200.100.0/24 network, serverb is configured with a single dhcp scope that has an ip address range from 10.200.100.10 to 10.200.100.100. all network computers are on a single physical segment.
several users on the network report that they cannot connect to certain file and print servers, but they can connect to each other’s computers. all other users on the network are able to connect to all network resources. you run the ipconfig.exe command on an affected computer named client1 and receive the results shown in the following table:
ip address 10.200.200.10
subnet mask 255.255.255.0
default gateway 10.200.100.1
dhcp server 10.200.100.5
dns server 10.200.100.6
primary wins
you need to ensure that all client computers can communicate with all other hosts on the network. which computer should you reconfigure?
你是pcjob的网络管理员，网络由一个单独的活动目录域组成，名为pcjob.com，该域包含有运行windows 2000 server、windows 2000 professional、windows nt server 4.0的计算机，在10.200.100.0/24网段，serverb被配置了一个单独的dhcp作用域，ip地址范围从10.200.100.10到10.200.100.100，所有网络计算机不在一个单独的物理网段。
一些网络中的用户报告说他们不能连接到当前的文件和打印服务器，但是他们可以连接到彼此的计算机，网络中所有的用户都可以连接到所有的网络资源。你在一台受到影响的名为client1的计算机上的运行ipconfig.exe命令并收到如上给所示结果。
你需要确定所有的客户计算机够与网络中的其他主机通信，你需要重新配置哪一台计算机？
to answer, select the appropriate computer in the network diagram.
在下图中的进行选择。
正确答案：client1
由于client1的ip地址是10.200.200.1，而网络中其他主机所处的网段是100.200.100.0/24，也就是说，client1与其他主机并不在同一网段内，所以，client1需要重新配置。
