How to Fix DHCP Log Error DNS Update Failed Error Code 31
1 Create a DHCP account in Active Directory, and make it a member of DnsAdmins
2 Make the following changes at the DHCP server
3 Make all the DHCP servers a member of DnsUpdateProxy in Active Directory.
4 Create reverse lookup zones accordingly at DNS server.
5 Restart the DHCP server.
Does the DHCP account need to be in DNSadmins group? The MS documentation says it only needs to be a standard domain user….
yes, you are right, it doesn’t need to be in DNSadmins group according to Microsoft. We have a mixed environment, mac, non-domain computers, phones, etc. I found out that adding it to the DNSadmins group helps all the devices (domain and none domain) update their records correctly.
