Windows dns record failover

You can specify up to 5 IP addresses for each of your hostnames. The steps to configure DNS Failover are as follows:. We will add a root record an A record with the name field left blank to the domain example. You can learn more about recommended TTL values here. Set up a contact list for notification of the failover event by selecting Contact Lists from the Config drop-down menu.

Give the contact list an identifiable name and enter the email address es you would like included in the list, one per line. Otherwise, it should be part of whatever group is set up to have management permissions for the domain. Now we set up DNS Failover. I'm afraid it doesn't seem like the default behavior and we may need some more research.

Before that would you please try manually registering on the non Windows client? Does the record look the same as the normal ones? Is there a timestamp?

MX records have a blank hostname record. What mail system are you using? If a third party mail server, if you create two "email" records with different IP addresses, then those two IP addresses must have a duplicate whether replicated or clustered between the two mail servers, otherwise if the CLIENT access one of the IPs and the mail database on that IP does not have the client's mailbox, then the client will not be able to access their email.

As for the MX records, as I mentioned, it's not for client use, rather for other mail servers to find your domain's mail server. For client use, as long as you have multiple mail servers no matter what vendor Exchange or otherwise , you can create multiple A records with the same same but each with a different IP address.

This way Round Robin will rotate between them. It's not a true failover, rather more of a load balancing mechanism. True failover would be on the mail server configuration end, not DNS or the client, that is if the mail server you use truly supports it.
