Dns updating

Some customers have reported issues with Microsoft Dynamic Updates after installing virtual appliances (VAs) in their environment or installing the Umbrella Roaming Client on some machines.

The most commonly reported symptom is that clients cannot resolve A or PTR records for other client machines while using the VAs or the Roaming Client for DNS resolution.

The below document provides instructions on how to update A and SPF records with some popular domain registrars.

Part of setting up your domain with a cloud service like Office 365 operated by 21Vianet includes changing or adding DNS records for your domain, like MX records for email.

When either type of client (static or DHCP client) initiates an A record update with its authoritative DNS server, it will first start by performing an SOA query for the FQDN of the client in question: The client then receives a response from the authoritative DNS server containing information about the server that is to process the dynamic update.

From there, the client continues communicating with the primary DNS server that accepted the A record update.

If you don't want your new site to start displaying for everyone, don't change the DNS settings.
