Security Alert Dialog Box Appears When Launching LabVIEW on Windows XP SP2



Primary Software:
Primary Software Version: 7.1
Primary Software Fixed Version: N/A
Secondary Software: LabVIEW Development Systems

Problem:
When I launch LabVIEW or the NI Example Finder for the first time on Window XP Service Pack 2, I receive a Security Alert dialog box with the following message:

To help protect your computer, Windows Firewall has blocked this program from receiving unsolicited information from the Internet or a network.

Solution:
Microsoft included additional network protection by enabling a firewall by default in Windows XP Service Pack 2. This firewall can affect LabVIEW and applications created in LabVIEW.

If you select the Keep blocking this program option, the LabVIEW VI Server, LabVIEW Web Server, and any server written in LabVIEW cannot accept incoming connections from a remote computer. Select the Unblock this program, despite the security risk option to configure your computer to launch LabVIEW without any changes in functionality.

If you have administrator access, you can configure the Windows firewall by using the Windows Firewall Control Panel applet. To give LabVIEW permission to receive incoming connections, select the Exceptions tab of the Windows Firewall dialog box, click the Add Program button and locate LabVIEW in the list or click the Browse button to navigate to LabVIEW.

If you want to give only specific LabVIEW servers permission to receive incoming connections, you can create exceptions by clicking the Add Port button. For example, if you want to block all LabVIEW servers except for the VI Server, you can add the port for the VI Server in the Add a port dialog box.
