GEN001375-ESXI5-000086 - For systems using DNS resolution, at least two name servers must be configured.

Information

To provide availability for name resolution services, multiple redundant name servers are mandated. A failure in name resolution could lead to the failure of security functions requiring name resolution, which may include time synchronization, centralized authentication, and remote system logging.

Solution

Open the vSphere/VMware Infrastructure (VI) Client and log in with appropriate credentials.
If connecting to vCenter Server, click on the desired host.
Click the Configuration tab and view the listed DNS server setting(s).

If DNS is configured has less than 2 servers configured, add a second server.
