DHCP server event logs now provide detailed information about DNS registration failures.

Note

In many cases, the reason for DNS record registration failures by DHCP servers is that a DNS Reverse-Lookup Zone is either configured incorrectly or not configured at all.

The following new DHCP events assist you to easily identify when DNS registrations are failing because of a misconfigured or missing DNS Reverse-Lookup Zone.

ID Event Value
20317 DHCPv4.ForwardRecordDNSFailure Forward record registration for IPv4 address %1 and FQDN %2 failed with error %3. This is likely to be because the forward lookup zone for this record does not exist on the DNS server.
20318 DHCPv4.ForwardRecordDNSTimeout Forward record registration for IPv4 address %1 and FQDN %2 failed with error %3.
20319 DHCPv4.PTRRecordDNSFailure PTR record registration for IPv4 address %1 and FQDN %2 failed with error %3. This is likely to be because the reverse lookup zone for this record does not exist on the DNS server.
20320 DHCPv4.PTRRecordDNSTimeout PTR record registration for IPv4 address %1 and FQDN %2 failed with error %3.
20321 DHCPv6.ForwardRecordDNSFailure Forward record registration for IPv6 address %1 and FQDN %2 failed with error %3. This is likely to be because the forward lookup zone for this record does not exist on the DNS server.
