ISSUE: Error code 5003 on Zoom when joining a meeting.
ACTIONS TAKEN:
Here are the steps that I performed on Daniel's machine to be able to connect the Zoom meeting link concern.
1. Open Control Panel > Network and Internet > Network and Sharing Center.
2. From the left menu, click on the Change Adapter settings link.
3. Right-click on the connection you’re currently using and select Properties, like the sample below.
4. Scroll down and click on Internet protocol version 4 (TCP/IPv4). Once it's selected, click the Properties button.
5. Select Use the following DNS Server addresses. Type 1.1.1.1 into the first row, then 1.0.0.1 into the second row.
6. Click OK to apply your changes.
7. Try to connect to the Zoom meeting link and see if the error has resolved.
You can always revert the settings back by repeating steps 1 to 4, and then select Obtain DNS Server address automatically.
