Windows XP Firewall and Device Discovery Issues

If you are using the Windows XP Firewall (XP SP2), you may have to follow these steps in order to enable the UPnP protocol so that Roku Radio Snooper can find your SoundBridge devices on your local network:

1. Open My Network Places

2. Click on "Show icons for networked UPnP devices" in the Common Task panel on the left side of the My Network Places window. If the Common Task panel is not visible

        a. Select Tools>Folder Options in the My Network Places window

        b. Under the Tasks section, choose "Show Common Tasks in Folders" and click OK.

3. Choose OK when asked to open the UPnP firewall ports.
