When you try to add a Windows Media Center Extender to a Windows Vista Media Center-based computer, you receive the following error message:

Extender Not Found
Setup could not find you Extender. Verify the Following

  • Your Extender is on and connected to the same network as this computer
  • Your setup key is correct
  • Your firewall is set up to allow UPnP Discovery


This issue occurs because the Windows Vista Media Center-based computer cannot find the Extender on the network.


Method 1

Verify that the Windows Vista Media Center-based computer and the Media Center Extender are connected to the same network.

Method 2

Determine whether firewall settings or privacy programs are preventing communication between the computer and the console.

For more information about how to configure your firewall or privacy programs, see the documentation from the manufacturer.

Method 3

  1. Install the latest driver for the network adapter on the computer. For more help about how to download and install the driver, contact the computer manufacturer.
  2. Use a different network adapter to help determine whether the network adapter is causing the issue.

Method 4

Verify that the computer is not joined to a domain. To determine whether Group Policy settings are causing the connection issue, temporarily remove the computer from the domain, restart the computer, and then again try to add the Media Center Extender.
