  • ONTAP 9 

问题描述

在配置要在Hyper-V部署中使用的持续可用(CA)共享时、见证协议将失败、Windows将生成以下事件日志条目:
Witness Client failed to find a Witness Server for NetName \ccp1filer with error (A remote procedure call (RPC) protocol error occurred.). Retrying in (15) seconds"。 从Windows Server 2012 R2客户端连接到CA共享时、用户可以成功映射此共享并创建/查看文件;但是、SMB 3.0见证协议会失败。

在Windows "MBWitnessClient"事件日志中、显示以下错误:
Log Name:      WitnessClientAdmin

secd日志中将显示以下内容:

在捕获见证协议握手的数据包跟踪中、客户端NTLMSSP_AUTH期间会注意到NTLMv2不存在:


集群模式Data ONTAP 8.

以下屏幕截图显示了SVM的响应:

通过对成功的见证协议握手的示例跟踪进行比较、可以清楚地看到NTLMv2:
