问题点：设置好共享后发现无法通过本机IP地址打开，提示找不到网络路径，只能通过\主机名进行访问，于是运行里面用\LOCALHOST及\127.0.0.1及试了下发现均显示找不到网络路径。于是点击修复，提示远程计算机或设备将不接受连接。如下图
禁用网卡甚至使用net winsock reset以后均无效。并尝试下载网上修复工具，均无果
使用netatat -an查看本地445端口，发现没有打开，
以下是综合网上的解决方案
分析：
1.先检查各项服务运行情况，发现都是在运行的，网络共享设置里面也全部打开了。
2.用netstat -an命令检查端口情况发现445端口没有打开。
3.445端口是SMB的服务端口，没打开要么是服务问题，要么是网卡问题。
4.检查本地连接的详细信息发现NETBIOS OVER TCP/IP的状态是禁用的。
5.一般情况下这个协议默认都是会开启的。
6.于是百度解决办法，各种设置及修改注册表，均告失败。
7.想到可以用nbtstat -a -127.0.0.1命令看下，结果返回提示netbt没有绑定任何设备。
8.也就是说netbt服务已经开启了，但是没有绑定到现有网卡上面，当然也无法工作了。
9.于是卸载网卡驱动（不删除驱动文件）后扫描硬件改动自动添加网卡。
10.结果错误提示仍旧一样。
11.想到电脑之前换过主板而系统没有重装，估计是网卡参数部分有错误或者冲突。
12.于是进注册表检查lanmanserver，netbt和netbios服务项的数值，发现有残留数值。
解决办法：
由此可见是因为netbt的参数里面未绑定当前网卡导致的，方法也就自然简单了，将netbt里面绑定的网卡清空，再通过卸载网卡和自动安装网卡驱动绑定netbt服务项即可。清空的办法可以导入如下注册表内容，导入后打开计算机管理——设备管理器——网络适配器——卸载网卡再扫描硬件改动。注意（卸载网卡设备不需要勾选卸载网卡驱动）
修复注册表内容如下，复制保存为.reg文件
