Appendix A
To manually configure or verify the configuration of Windows Live OneCare
1. Launch Windows Live OneCare.
2. Under Common Tasks, click Change OneCare settings.
3. Click the Firewall tab, and then click the Firewall connection tool
button.
4. Locate the entry for Connect my Media Center Extender to my Media
Center Computer. Select the check box next to this entry if it is not
already enabled, and then click Apply.
Additionally, the firewall protection level can affect connectivity. If the
protection level is set to Restricted, connectivity between the Windows
Media Center Extender and Windows Media Center will be broken. The
firewall protection level should be set to Automatic (recommended).
Configuring a non-Microsoft firewall
If you use a non-Microsoft firewall, you may need to manually configure
your firewall to allow Media Center Extender applications access to the
ports. A firewall vendor may ask you to configure the firewall in two
different ways.
1. Some firewall vendors want you to configure the firewall for the
actual application—in other words, to let the firewall know what
application(s) can access the ports.
2. Some firewall vendors may want you to configure the port or ports
the application is using.
During the firewall configuration process, you may also need to know
what network the application or port needs to work with. In the
configuration setting, a Local Subnet network means the application or
port is for use on the local (or your "home") network. Internet means the
application will talk to other computers on the Internet.
