It will remain so until all domain controllers have been moved over and all other records have been recreated. That can occur either via dynamic DNS or manually.
Some customers prefer to have the BlueCat Professional Services team assist with the migration effort. This is a more user-friendly alternative to requiring updates for all devices during a single maintenance window.
Executing this procedure correctly should result in zero downtime. It really depends on your primary DNS configuration. Seven in 10 enterprises struggle to realize the full value of their cloud investments.

There is a command line involved, but the effort is trivial.
Or, the command line net stop netlogon and net start netlogon also works. More complex migration needs The process outlined above will work fine for a simple domain.
Remove the migrated zones from Microsoft DNS. This browser is no longer supported. Download Microsoft Edge More info. Contents Exit focus mode. Note In addition to this topic, the following DNS content is available.
Is this page helpful? Yes No. It underpins critical server operations such as domain controller replication as well as client-server communications. Before working on AD configuration you should have a sound understanding of how DNS works, including knowledge of performing DNS diagnostics such as looking up a DNS record from an authoritative source in debug mode. Expand All. Microsoft Active Directory uses DNS to enable servers and workstations to locate services such as domain controllers running within the Active Directory namespace.
To support an Active Directory domain called example. The domain that you have registered for use on the internet either as a service provider, or as an internet client is called your external DNS namespace.
Domain controllers will be unable to register an A record resolving to their own IP address for the name of the domain unit. Although this is not generally an issue, it can break some functionality:.
If you are affected by either of the DFS issues, or if you think you may have discovered other functionality that is broken by these missing records, please contact us. You need to do is to choose a name for your domain that doesn't exist in global DNS and is never likely to exist.
We recommend that you use a subdomain of your DNS name such as unit-ad. You may already be using a subdomain of a top level domain such as unit-ad. If this is working for you then there is no immediate need to change. If you have a forest with more than one domain, or you need to set up trusts between two domains in different forests.
In all cases, make sure that your firewall configuration is correct, as described elsewhere on this page. Also make sure that the domain controllers, including the DNS servers, running in the different domains can communicate with each other through any firewalls that are between them.
When using your primary DNS namespace for your AD with the Option 1 configuration above then everything should work with minimal additional configuration. Configuring name resolution between multiple domains when separate internal DNS namespaces requires each domain to be manually configured with the DNS server settings for the internal namespaces. The following options are suggested but untested:. Additional tools that IT Services use for diagnosing security and configuration issues will only apply for clients using the central servers.
If using the central servers, make sure that firewalls are configured correctly as per the previous section or lookups routed through the central resolvers may fail. This can cause application problems if the client Windows name does not match the first part of its registered DNS name. The simplest solution to this issue is to make sure that the names match. Please ensure that you disable the default Windows option on clients to register the computer name and IP address in DNS at boot time.
This causes extra load on the Oxford DNS servers and will result in errors being logged that may confused diagnosis of network or AD problems.
