Hi friends,
i have a sql cluster with alwayson and today i noticed a scenario.
When I restarted the domain / dns server that is my quorum when trying to authenticate to the databases I had difficulty and generated several failures in the cluster of quorum unavailable.
So I asked myself regarding the importance of the availability of my domain controller server to access the databases.
However I have another domain controller server (secondary) which is also DNS.
Can anyone tell me how long it takes servers that authenticate to the domain/dns server need to direct connections to the secondary server?
Can this be adjusted to be faster?
Thanks.
