Otherwise the client doesn’t know what zone name to register in. The Primary DNS Suffix MUST matches the zone name that is allowing updates. the minimal requirement of "." "domain.local," etc).Ģ. Active Directory’s DNS Domain Name is NOT a single label name ("DOMAIN" vs. "Moreover, applications that you might not think are using IPv6-such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail-could be."ġ. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. "IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. The Cable Guy – Support for IPv6 in Windows Server 2008 R2 and Windows 7, by Joseph Davies, Microsoft, Inc. If disabled, it will cause other problems: For Windows 2008 and all newer operating systems, IPv6 must not be disabled. Published by Ace Fekay, MCT, MVP DS on at 6:25 PM 641 0ġ1. More info on this:Īctive Directory DNS Domain Name Single Label Names – Problematic ISC has made a note of the excessive traffic generated by Microsoft DNS servers configured with a single label name in 2004 with Microsoft, which in turn disabled the ability for Microsoft DNS in Windows 2000 SP4 and newer to resolve single label names without a registry band aid. Single label name zones are problematic, do not conform to the DNS RFC, and causes excessive internet traffic to the Root Servers when DNS tries to resolve a single label name query, such as querying for computername.domain – in such a query, the domain name is actually treated as a TLD. The zone in DNS must NOT be a single lable name, such as "DOMAIN" instead of the required minimum of two hierarchal levels such as, domain.local,, domain.you, etc.
This is default and expected behavior, but if there are any DCs that have any problems, and the client resolved the SOA to that DC, it may not accept the update.ġ0. Keep in mind with AD integrated zones the SOA rotates among the DCs because of the multimaster feature. If the SOA is not available or resolvable, it won’t register. The client will "look" for the SOA of the zone when it attempts registration. If the zone is single label name, such as ‘domain’ instead of the proper minimal format of ‘,’ ‘,’ etc., it will NOT update.ĩ. If the DNS server is multihomed and not configured properly to work with multihoming, it may cause problems with Dynamic Updates.Ĩ.
For any non-Windows statically configured machine, it must support the DNS Dynamic Updates feature and the zone configured to allow Secure and Unsecure updates.ħ.

For non-joined domain DHCP clients, you can configure DHCP to update in lieu of the client updating into a Secure Only zone.Ħ. If statically configured and not joined to the domain, the client can’t update if the zone is set to Secure Only.Ĭ. – It must be joined to the domain in order to authenticate using Kerberos to update.ī. If the machine’s DNS is statically configured: For AD Integrated Zones and Secure Only Updates:Ī. The Zone must be configured to allow updates.ĥ. If using DHCP Option 015 (Connection Specific Suffix), it must match the zone name and have "Use This Connection’s DNS Suffix in DNS Registration" along with "Register This Connection’s Addresses in DNS" checked in the NIC’s IPv4, Advanced, DNS tab.Ĥ. For non-joined machines, it must be manually configured or scripted.ģ. The Primary DNS Suffix on the machine MUST match the zone name in DNS.ī.
DHCP Option 006 MUST only be the internal DNS server(s) you want to use, otherwise if using an ISP’s DNS or your router, expect undesired results.Ģ. The machine’s DNS entries in the NIC, must be ONLY configured to use the internal DNS servers that host the zone. Keep in mind, for the most part it automatically works "out of the box" without much administrative overhead.ġ.
