问题 问答题

在网络中,有一台Windows 2000客户机启动时无法访问Internet,运行ipconfig/all命令后显示MACidi址为00-00-E8-6E-24-2F,IP地址为0.0.0.0,子网掩码为0.0.0.0,DHCP服务器地址是255.255.255.255。请列出可能出现的硬件和软件故障。

答案

参考答案:硬件故障:传输介质故障(包括网线、信息插座、配线架等故障)、设备故障(包括集线器、交换机出现故障)
软件故障:DHCP服务器故障(包括配置不正确或没有可租约的IP地址)

解析:从ipconfig/all命令执行结果看,这台工作站没有租约到IP地址。引起这一故障可能有硬件故障,也可能是软件故障。硬件故障主要包括传输介质故障(包括网线、信息插座、配线架等故障)、设备故障(包括集线器、交换机出现故障),软件故障可能是DHCP服务器故障,包括DHCP服务器配置不正确或DHCP服务器没有可租约的IP地址。

     A new guidebook says being_happy_is_just_like_being_fit-you need to practice the skills

needed to get this emotion,even during the darkest times.

     Roadtesting Happiness:How to be Happier by Australian journalist and author Sophie

Scott is a selfhelp book with a difference."Being happy is something you need to focus on;

it doesn't come as a matter of course,"  Scott said."You always need to make an effort to be

happy,even if you reach the point of saying you are contented,you still need to keep focusing

and working on the things that made you happy." Scott also said the book was born out of her

interest in the human mind as well as how difficult she found it to cope after her mother died of

cancer two years ago.

     "I was always interested in psychology,but a lot of happiness books don't address the fact that

you can be happy even if your life isn't going according to plan.The key is managing expectations."

She says,"In the book,I focused on what were the things most likely to make people happy,the

ones with the most scientific evidence."  People should think that being happy is yet another task

you have to do and then feel guilty when you don't do it.Scott says the road to a positive outlook

begins with very easy,small steps.

     "Women in particular today______________:they've got to be thin,got to have a career,got

to have a perfect relationship so the last thing you need is to be thinking you've got to be happy

all the time,"  she said."But it is important to improve your quality of life.Stop rushing around and

filling each moment of the day with things to do,and then sit down and think about your life and

how you're feeling.The things I got out of this were not things that take a lot of effort:feeling more

grateful for the things you've got;adjusting your reaction to situations and people.It's about changing

small habits,more tinkering around the edges instead of totally checking and changing your life."
