Without an associated domain name. When the resolver builds a DNS query for an unqualified hostname, the hostname is extended to a fully qualified domain name before the query is passed to the name server. The domain name the resolver appends to the hostname depends on which options are selected.When the “Append primary and connection specific DNS suffixes” option button is selected, the primary domain name and the domain name associated with this connection are used to fully qualify unqualified hostnames. The domain name associated with the connection is the domain name entered in the “DNS suffix for this connection” box near the bottom of the DNS tab. In Figure 4-7, the sample value entered in this box is sales.example.net. The primary DNS suffix, however, is not configured through this window. It is configured on the Computer Name tab of the System Properties dialog. To configure the primary DNS domain name, go to the Start menu, open the Control Panel menu and select System. In the System Properties window, select the Computer Name tab. Click Change to open the Computer Name Changes window. Then click More to open the DNS Suffix and NetBIOS Computer Name dialog. In the “Primary DNS suffix for this computer” box, enter the primary domain name for this computer. Figure 4-8 shows this dialog.Figure 4-8. The DNS Suffix and NetBIOS Computer Name dialogGiven the values in Figures 4-7 and 4-8, the primary DNS suffix for this system is plant.example.com, and the DNS suffix for this connection is sales.example.net. The “Append parent suffixes of the primary suffix” checkbox impacts how these domain names are used. If the checkbox had been selected with the settings shown in Figures 4-7 and 4-8, a request for the IP address of mandy generates a query for mandy.plant.example.com, then one for mandy.example.com (assuming the first query was not successful), and finally one for mandy.sales.example.net (assuming the second query was not successful). The system does not, however, search example.net, which is the parent domain of sales.example.net. If the “Append parent suffixes of the primary suffix” checkbox is not selected, a query for mandy would generate a query for mandy.plant.example.com and then one for mandy.sales.example.net. No parent domains would be searched.Defining your own domain search list is the alternative to using the primary and connection DNS suffixes. To define your own search list, click the “Append these DNS suffixes (in order)” option button. This

Active Directory setup:Single forest, 3 domains, with 1 domain controller each. All running server 2008 R2, with the same domain/forest functional level.DNS clients are configured as follows:DC1 -> DC2 (prim), DC1 (sec)DC2 -> DC1 (prim), DC2 (sec)DC3 -> DC1 (prim), DC3 (sec)All zones are replicated throughout the entire forest, and each DNS server is set-up with 8.8.8.8/8.8.4.4 as forwarders.Problem:Everything appears to be working as should. AD is replicating properly, DNS is responsive and not causing any issues, BUT when I run dcdiag /test:dns, the enterprise DNS test fails on DC2 and DC3 with the following error:TEST: Forwarders/Root hints (Forw)Error: All forwarders in the forwarder list are invalid.Error: Both root hints and forwarders are not configured orbroken. Please make sure at least one of them works.Symptoms:Event viewer is constantly showing these 2 event ID's for DNS client:ID 1017 - The DNS server's response to a query for name INTERNAL RECORD indicates that no records of the type queried are available, but could indicate that other records for the same name are present.ID 1019 - There are currently no IPv6 DNS servers configured for any interface on this host. Please configure DNS server settings, or renew your dynamic IP settings. (strange, as IPv6 is disabled on the network card)nslookup is working as expected, and finding any and all records appearing in ID 1017, no matter which DNS server I select to use.While running dcdiag, the following events appear:Event ID 10009: DCOM was unable to communicate with the computer 8.8.4.4 using any of the configured protocols.DCOM was unable to communicate with the computer 8.8.8.8 using any of the configured protocols.Event ID 1014: Name resolution for the name 1.0.0.127.in-addr.arpa timed out after none of the configured DNS servers responded.I've run wireshark while dcdiag is running its test, and the internal DNS servers do resolve anything thrown at them, but then the server continues querying Google DNS and root hints.What the hell is going on? What am I missing here?Edit: The actual enterprise DNS test error messages are: Summary of test results for DNS servers used by the above domain controllers: DNS server: 128.63.2.53 (h.root-servers.net.) 1 test failure on this DNS server Name resolution is not functional. _ldap._tcp.domain1.local. failed on the DNS server 128.63.2.53 DNS server: 128.8.10.90 (d.root-servers.net.) 1 test failure on this DNS server PTR record query for the 1.0.0.127.in-addr.arpa. failed on the DNS server 128.8.10.90 Name resolution is not functional. _ldap._tcp.domain1.local. failed on the DNS server 128.8.10.90 DNS server: 192.112.36.4 (g.root-servers.net.) 1 test failure on this DNS server Name resolution is not functional. _ldap._tcp.domain1.local. failed on the DNS server 192.112.36.4etc., etc.

Names when you use conditional forwarding.The local DNS server (10.100.100.70) can connect to the DNS server that's configured as a conditional forwarder (10.133.3.250). The first request from the DNS server to the conditional forwarder successfully resolves a name (for example, nbob1.contoso.com). After some time, name resolution stops working. An nslookup query to the conditional forwarder returns a "nonexistent domain" error message.If you clear the DNS server cache on the forwarding computer (the local DNS server), name resolution resumes. However, this fix is temporary.To troubleshoot this issue, see Forwarded DNS name resolution fails for dual-stacked queries.DNS Server loses its NIC Teaming configurationConsider the following scenario:The DNS server computer has multiple network adapters that you use in a NIC Teaming configuration.You configure the DNS server to listen on the IP address of the teaming network adapter.On the Interfaces tab of the DNS server properties dialog box in DNS Manager, you can configure the IP address that you want to use.After you restart the DNS server, Windows deletes the setting. The DNS server starts listening on all IP addresses again.When this change occurs, Windows logs Event ID 410 in the DNS server event log:The DNS server list of restricted interfaces does not contain a valid IP address for the server computer. The DNS server will use all IP interfaces on the computer. Use the DNS manager server properties, interfaces dialog box, to verify and reset the IP addresses the DNS server should listen on. For more information, see "To restrict a DNS server

DNS Agent for Mavericks DNS Agent is suitable for use in a machine with a dynamically assigned IP address. Whenever the IP address changes, DNS Agent will update the DNS Server that is managing that machine's domain-name to IP-address mapping, thereby keeping that machine's domain name in sync with its IP address at all times.. DNS Agent is able to update two kinds of DNS Servers - BIND name servers set up by DNSEnabler (Lion, Mountain Lion, or Snow Leopard versions), or dyndns.com servers. Upgrade Notes, if you’ve used DNS Agent before and didn’t do a clean install of Mavericks:Once you have launched the latest version of DNS Agent, save the current config using the File->Save menu item, do a De-Install from the Help menu, which removes all the previous cruft, and then quit and come back to the app. You'll then get the config files, libraries and the other stuff that will work with Mavericks. Introduction You need to be an admin-level user to use DNS Agent and the machine it is running on must already have a domain name managed by some DNS Server. After logging in, depending on whether the DNS Server is managed by DNS Enabler , or one managed by dyndns.com, go to the relevant DNS Agent tab panel. DNS Server managed by DNS Enabler Note : The DNS Server must be running either DNS Enabler for Lion, Mountain Lion, or the Snow Leopard version, in order to have the dynamic DNS update capability. DNS Enabler can be made to generate an Authorisation Key for DNS Agent to use so that it can identify itself to the server as a valid client. DNS Agent can monitor the machine's IP address as seen on its Network Preferences Panel in System Preferences, or poll checkip.dyndns.com for its
