Hi
Our ACS has begun getting Alarms for "Configured nameserver is down Server=<Primary / Secondary ACS hostname>." The Alarm Details say, "Please check DNS configuration, check corresponding DNS server and domain controller are available." DNS configuration is correct and DNS servers are available all the time. This Alarm occurs intermittently (a total of several times / week) at random times of the day on both Primary and Secondary ACS.
This particular alarm started after I upgraded ACS from 5.6 to 5.8 patch 6 back on 1/31/2017. ACS never got this Alarm on 5.6 or any other previous versions. ACSs are virtual.
Anybody have suggestions to remedy?
Thanks,
Mike
