<![CDATA[DNS lookup on status polls stopped working]]>Sometime in the last few months, as we upgraded to one of the new versions of NetXMS, DNS lookups on status polls appear to have stopped working, and our dynamics DNS nodes aren't getting status polled anymore.
The option Objects.Nodes.ResolveDNSToIPOnStatusPoll is properly set to 1.
We're running version 3.8.226.
It looks like this could be a regression bug.
Please assist.

are those nodes in default zone or in remote zones? If yes and zone proxy cannot resolve host name then server will not attempt to resolve it directly unless server configuration parameter Objects.Nodes.FallbackToLocalResolver set to true. This change was introduced in version 3.5.

Best regards,
Victor

please verify with command show flags in server debug console if flag AF_RESOLVE_IP_FOR_EACH_STATUS_POLL is actually set.
