最近项目需要配置DNS 发现网络连接打开后是空白 无法显示“本地连接”，在服务列表中也找不到，试了几种办法都不行，最后在http://blog.csdn.net/wangxiaofei2006/article/details/6833168中找到了解决办法，确认是安装如网络人之类的网络监控软件造成的。
解决步骤：
1、新建一个记事本，将下面的复制到记事本文件，改名REG，点击运行它，添加注册。
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNetman]
"DependOnService"=hex(7):52,00,70,00,63,00,53,00,73,00,00,00,00,00
"Description"="Manages objects in the Network and Dial-Up Connections folder, in which you can view both local area network and remote connections."
"DisplayName"="Network Connections"
"ErrorControl"=dword:00000001
"ImagePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,
74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,
00,76,00,63,00,68,00,6f,00,73,00,74,00,2e,00,65,00,78,00,65,00,20,00,2d,00,
6b,00,20,00,6e,00,65,00,74,00,73,00,76,00,63,00,73,00,00,00
"ObjectName"="LocalSystem"
"Start"=dword:00000003
"Type"=dword:00000120
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNetmanParameters]
"ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,
00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,
6e,00,65,00,74,00,6d,00,61,00,6e,00,2e,00,64,00,6c,00,6c,00,00,00
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesNetmanEnum]
"0"="Root\LEGACY_NETMAN\0000"
"Count"=dword:00000001
"NextInstance"=dword:00000001
2、注册regsvr32 netman.dll ，开始---运行--regsvr32 netman.dll
3、启动服务开始---运行--cmd里输入（这一步提示失败 我是直接跳过执行的第四部）
sc Network Connections enable
net start Network Connections
4、重启系统
注意事项：如果注册netman.dll说找不到组件时，从同类操作系统中拷贝一个过来，放在system32 目录下，并注册之！
