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. |
| 20322 | DHCPv6.ForwardRecordDNSTimeout | Forward record registration for IPv6 address %1 and FQDN %2 failed with error %3. |
| 20323 | DHCPv6.PTRRecordDNSFailure | PTR record registration for IPv6 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. |
| 20324 | DHCPv6.PTRRecordDNSTimeout | PTR record registration for IPv6 address %1 and FQDN %2 failed with error %3. |
| 20325 | DHCPv4.ForwardRecordDNSError | PTR record registration for IPv4 address %1 and FQDN %2 failed with error %3 (%4). |
| 20326 | DHCPv6.ForwardRecordDNSError | Forward record registration for IPv6 address %1 and FQDN %2 failed with error %3 (%4) |
| 20327 | DHCPv6.PTRRecordDNSError | PTR record registration for IPv6 address %1 and FQDN %2 failed with error %3 (%4). |
