nessus扫描时出现如下情况：
Network interface transient error
The network interface ‘\Device\NPF_{DF6D9295-830F-4A92-B0E4-D0C0C9188C87}’ was not always available for packet forgery, which may lead to incomplete results. This is likely to be a transient error due to a lack of resources on this host. To correct this error, reduce the number of scans and/or hosts scanned in parallel
是因为当前电脑没有安装winPcap，或者是winPcap不是最新版本
解决办法：
安装最新winPcap即可
winpcap作用网络捕获，捕获当前电脑上每一个网卡的数据包
