实用netsh命令备份网络配置

如果用户使用笔记本电脑，并经常往来于家庭和公司之间，那么备份网络配置即可避免在网络配置改变之后重新配置。在windows98系统下可以使用"ipconfig /batch bak-netcfg"命令备份网络配置。在windows2000/XP系统下，可以使用netsh命令。
要把主机上的所有网络相关的配置信息备份到C盘test.txt文件，可以运行命令：
netsh dump>c:\test.txt
要把本机中远程访问连接和TCP/IP配置接口参数备份到C盘下的test.txt，可以运行命令：netsh interface dump>test.txt。
示例如下：
C:\>netsh dump>c:\test.txt，然后我们就可以在c盘找到test.txt文件，改文件的内容如下：

以后在进行网络设置调整时，如果发生了操作错误，或者服务器网络出现故障，可以利用备份快速恢复网络设置：
netsh -f c:\test.txt或netsh exec c:\test.txt
要把主机上的所有网络相关的配置信息备份到C盘test.txt文件，可以运行命令：
netsh dump>c:\test.txt
要把本机中远程访问连接和TCP/IP配置接口参数备份到C盘下的test.txt，可以运行命令：netsh interface dump>test.txt。
示例如下：
C:\>netsh dump>c:\test.txt，然后我们就可以在c盘找到test.txt文件，改文件的内容如下：
