You should only change this setting if you are experiencing problems receiving RealAudio and RealVideo clips or you have been notified by your network administrator that you should change this setting. Requirements: RealPlayer G2, 7.0, 8.0 installed. It may be necessary to first install the ISA Firewall Client prior to RealPlayer configuration. Please refer to "Installing the Microsoft ISA Firewall Client." To configure RealPlayer to use TCP to stream content: 1. In RealPlayer, click View from the main menu bar at the top of the RealPlayer window, and select Preferences. 2. Click on the Proxy tab. 3. Click on the radio button to select Use my web browser's HTTP proxy. (Your web browser should already be configured to use proxy server 10.100.1.2 and port 8080. If you have installed the ISA Firewall Client, the server name may say "Borderguard".) You should see a screen similar to the one below. 4. Click on the Transport tab. 5. Click on the Auto-Configure button. 6. Click on the OK button to begin auto-configuration. 7. RealPlayer will now auto-configure. 8.
