Windows Firewall

If you are using the Windows Firewall, you may notice the following behaviors in MAX:

• Microsoft Windows XP with Service Pack 1 (SP1) installed If the Microsoft Windows XP Internet Connection Firewall (ICF) is enabled, you cannot discover or install software to LabVIEW Real-Time targets unless you disable the ICF before browsing to these devices. Perform the following steps to disable the Internet Connection Firewall:
  1. From your desktop, open Network Connections by selecting Start»Control Panel»Network Connections.
  2. Double-click the connection you want to modify.
  3. Click Properties.
  4. On the Advanced tab, clear the Protect my computer and network by limiting or preventing access to this computer from the Internet checkbox.
• Microsoft Windows XP with Service Pack 2 (SP2) or later installed, or
  Microsoft Windows Vista
  When you update software on a LabVIEW Real-Time target while the Windows Firewall is enabled, a dialog box may prompt you to allow MAX to receive information over the network. Select Unblock this program so that MAX can communicate with your LabVIEW Real-Time target.

For more information on MAX and the ICF in Windows XP SP1, refer to the NI KnowledgeBase document 2WTAMTPK.
