Firewall

WMI (Windows Management Instrumentation) access must be permitted by Windows Firewall if the firewall is enabled using default settings. You can configure the firewall to allow WMI access by executing the following in a command prompt on the managed device:

netsh firewall set service RemoteAdmin

****Please note:
After installing Service Pack 2 on Windows XP, Windows Firewall is enabled by default. Please check the firewall configuration after applying SP2 to Windows XP devices that you plan to monitor with Longitude.

Problems monitoring external servers can be related to Domain security or firewall issues. Installing a Longitude Agent at the remote site will allow you to specify an account with different permissions for WMI collections, and will use specified ports through a firewall.

Longitude agents use the following ports:

• 7220 (TCP), for data collection
• 7223 (TCP), for data collection if using SSL
• 7229 (TCP), for upgrades
