Error updating dynamic dns entry
If you are working with, well almost anything network intensive these days, like Antivirus or management tools, your Reverse DNS (r DNS) lookups need to be in good shape.
Also, the ip information for the NIC is correct(ip, subnet, gateway, dns servers etc.) and the check box to update dns is checked. The update client periodically checks your network’s IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your Dyn account.If you’re like many Dyn DNS customers, you have a dynamic IP address which changes periodically (monthly, weekly or even daily).Finally, do the following: Update your domain's NS records to point to Office 365.When the NS records have been updated to point to Office 365, your domain is all set up.Email will be routed to Office 365, and traffic to your website address will continue to go to your current website host.

The computer gets disconnected from the VPN and get connected straight to the network but the DNS doesn't update the hostname with the new IP.
An update client is a computer application or a feature in your router that keeps your hostname’s IP address up-to-date.

It is an issue on Server 2000, 2003, 2008, 2008R2, Server 2012, Server 2012 R2 and will likely be an issue in the newer builds.
I recently changed a server's ip address to a static address from a dhcp address and after doing so the entry in DNS will not update.
