DHCP Logging Events for DNS Registrations
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). |
