We are using Skype for Business Server 2015 (6.0.9319.0)
We have tested SQL instance failover from node 1 to node2, when SQL instance is failed over to node2,
my users were able to log to skype but skype status shows limited functionality.
i can see the below error please help me to troubleshoot
[Exception=System.Data.SqlClient.SqlException(0x80131904): The target principal nae is incorrect.
Cannot generate SSPI context.
