故障现象：
访问文件服务器，提示The network location cannot be reached。
不能访问共享－The network location cannot be reached
 
用IPCONFIG /ALL发现NetBIOS over Tcpip ...   Disabled（还原故障，所以没有设置IP地址）
不能访问共享－The network location cannot be reached
但是在设备管理器中却没有禁用NetBIOS over Tcpip 。（显示隐藏设备，“非即插即用驱动程序”）
不能访问共享－The network location cannot be reached
解决办法：
删除网卡驱动，重启电脑，重新安装网卡驱动，故障解决。
 
曾经尝试过的方法，但未能解决问题：http://support.microsoft.com/kb/946937
1. Run Registry Editor (regedit.exe), and check the following registry key:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters]
2. Please find if the "TransportBindName" value exists. If either of them does not exist, create it. If either one is incorrect, change the data. The values should be like this:
Name: TransportBindName
Type: REGSZ
Value: \Device\
3. Under the same registry key, if you find the "SMBDeviceEnabled" value exists and is 0, it means Direct Hosting is disabled. You may change it to 1 to turn on it unless there are requirements that this should be disabled.
Name: SMBDeviceEnabled
Type: REG_DWORD
Value: 1
