Windows Update Client Install Guide (v5)

Watch this video or follow the instructions below to learn how to install and set up the Dyn Dynamic DNS Update Client.

Before you begin, you will need to:

Download the Dyn Update Client for Windows

Installation and Configuration

Note: Before installing the Dyn Updater, make sure ALL previous dynamic DNS update clients have been uninstalled from your computer.

1. In your Dynamic DNS account, go to Account Settings and find your Updater Client Key. If the Updater Client Key field is blank, click Generate Key. Note: Generating a new Updater Key will override the password on any other existing DDNS update clients attached to your account. This means that you will have to distribute the new key to any existing update client linked to your Dynamic DNS account. Note: If you are setting up DDNS for Managed DNS, visit our Managed DDNS guide.
2. Locate the file DynUpdater.msi on your computer and Double click the icon to run it. Note: If you’re not logged in as an administrator, you may need to right-click DynUpdater.msi and select Run as administrator.
3. Open the Dyn Update Client from your system tray and click Add Account. Enter your Dyn account username and use the Updater Client Key as your password.
4. Click the check box beside your one of your hostnames, and then click Configure Selected Host.
5. Ensure that Automatic is selected from the IPv4 Configuration drop-down menu,and then click OK. Your hostname will automatically be updated when your IP address changes.

Other Configuration Options

In Configure Selected Hosts screen, there are several options to choose from as defined here:

IPv4 Configuration: The option you select here controls how the IPv4 record of your hostname is updated. IPv4 is the older, more common, IP address protocol in use. IPv4 addresses look like 123.123.123.123
IPv6 Configuration: The option you select here controls how the IPv6 record of your hostname is updated. IPv6 and IPv4 records can co-exist on a hostname, allowing whoever is connecting to the hostname to use what protocol is available to them. IPv6 is the newer, less common, IP address protocol in use. If you do not have IPv6 connectivity through your ISP, you should disable this option to avoid updates not occurring. IPv6 addresses look like 2600:200f:1:1234:abcd:ef12:3456:789a.
Automatic: This option uses the address on which your machine connects to the public Internet, as seen by a remote server. This is the most commonly desired configuration.
Disabled: Do not create a record for this IP address protocol when sending updates. Disabling both protocols disables all updating for a hostname.
Local Interface: Provides of a list of interfaces to choose from when selected. When sending updates, this uses the first IP address found on the specified interface. This is useful to update a hostname to an internal IP address of a machine.
Static Address: Provides a text field to enter an address when selected. When sending an update, this exact address is used for this IP protocol. This is useful to have one IP address protocol detected automatically in some way, with the other set to a specific address always.

Status

Green – (Normal) Your hosts are up-to-date.
Orange – (Warning) The Dyn Updater requires your attention. Common reasons for receiving a Warning message include:

The Updater has submitted the same IP address multiple times within a period of 2 days. To reduce load, Dyn requests that you only update your hostnames if their IP addresses change. If you see multiple Warning messages in your Logs, you should determine the problem immediately, otherwise your account may be blocked due to abuse.
Running multiple update clients on one computer, such as version 3.0 and version 4.0 simultaneously.
Running multiple update clients on the same network, such as dynamic DNS software on your router, and an update client on your computer.
Fresh installation of the Dyn Updater, where all your hosts were already up-to-date.

Red – (Critical) The Dyn Updater has received an unrecoverable error. Some causes for a Critical status are:

Invalid account information (username or password is incorrect).
Invalid query sent to Dyn, Check your Internet connection to make sure data is being transmitted correctly.
Your account has been blocked due to abuse.

Once you have corrected the source of the critical error, you may click on View Details followed by Retry update to reset the Updater.
