To force a dynamic update of the DNS record, you can follow these steps:

1. Open the command prompt: Press the Windows key + R, type cmd, and hit Enter.

2. Type the command "ipconfig /registerdns" and hit Enter. This will initiate a dynamic update of the DNS record.

3. Wait for the update to complete. This may take a few minutes depending on your network configuration.

Alternatively, you can force a dynamic update of the DNS record by restarting the DNS Client service:

1. Open the Services console: Press the Windows key + R, type services.msc, and hit Enter.

2. Scroll down to the DNS Client service and right-click on it.

3. Click on Restart. This will force a dynamic update of the DNS record.

In order for dynamic DNS updates to work, your DNS server must support dynamic updates and be configured to allow updates from the client.
