摘　　要：针对局域网中计算机无法上网、网速变慢等关于管理和安全的一些典型问题,给出了相应的解决方案.当局域网中计算机无法上网时,可采用检查网卡I、P地址设置、双绞线连接等方法排除故障;当局域网网速变慢时,可采用检测网线、回路、硬件、端口等方法排除故障.采用帐号和密码保护、关闭不需要的服务和端口、适时启用还原卡、使用防火墙等方法解决局域网的安全问题.应用证明,以上方法可靠而且有效.In terms of some typical problems in management and the security of networks such as computers cannot be connected to the Interact, network speed gets slow, etc., this paper presents corresponding solutions. When computers in LAN cannot be connected to the Intemet, problems can be solved with checking network cards, IP address setup, and twisted-pair line connection. When network speed becomes slower, it is necessary to check the network cable, loop, hardware, ports, etc. to solve the problem. Measures such as protecting accounts and passwords, closing unnecessary servers and ports, starting restoration cards, using firewall, etc. can be taken to solve security problems in the LAIN. Practice proves to be reliable and effective.
