HP MediaSmart Server User's Guide The Firewall is Blocking the Connection If using a firewall program, configure it to allow any HP MediaSmart or Windows Home Server applications. For instructions to unblock, see the software vendor's documentation. What do Firewall Blocking Messages Mean? Firewalls block certain types of communications between network devices. This helps protect your data from hackers, viruses, spyware, and Trojan horse software. The computer might have one or more firewall programs installed. For example, if the latest version of the Microsoft Windows XP operating system is installed, the computer may be using the Windows XP Firewall. The HP MediaSmart Server comes with software applications that must communicate over the network. Sometimes these programs are blocked by a firewall. When this happens, security alerts pop up on the computer screen. Security alerts usually have a list of possible options. The particular messages or alerts displayed depend on the vender. For example, the alert might offer the following options: • Keep Blocking • Unblock • Defer the choice and be reminded later If a security alert dialog box for an HP MediaSmart Server application or the Windows Home Server is displayed by the firewall, click Unblock or Allow to permit the application to execute. It is safe to unblock the communications because no connection or communication with the Internet is enabled, only those between the server and its software applications. After unblocking an application, if any software is reinstalled, moved to a new disk location, or if the application is deleted from the exception list using the Windows XP Security Center control panel, communications between that software and the server may once again be blocked by the firewall. 134
