SYMPTOMS
On a computer that is running Windows Vista, if you configure a firewall after you install a Windows Media Center Extender device, the device may not work.



CAUSE
This problem may occur because the firewall closes ports that must be open for the Windows Media Center Extender device to work.



RESOLUTION
If you configure a firewall after you install a Windows Media Center Extender device, you must manually configure the firewall to open the following ports.

The procedure that you use to manually configure these ports is different for each firewall model and for each firewall manufacturer. For more information about how to configure your firewall, see its documentation.
