You can unregister a vCenter Server system from the vSphere Web Client if you no longer want users to use that vSphere Web Client instance to connect to the vCenter Server system.

Log-in to the system on which the vSphere Web Client is installed. You cannot unregister a vCenter Server system from a remote system.

Ensure that you have login credentials with Administrator privileges for the vCenter Server system that you are registering.

1

Open a Web browser and enter the URL for the administration tool: https://localhost:9443/admin-app or https://127.0.0.1:9443/admin-app.

Use the localhost or loopback address to access the administration tool instead of using the server IP address.

2

Select the vCenter Server system to unregister.

Click Unregister vCenter Server.

Type the username and password and click Unregister.
