DeviceControl Operation Manual 11
5.1.1 No Subnets found fault
If DeviceControl does not locate any available NLB
60E on the network, a pop-up window appears
(Figure 5.3).
If you are certain that subnets have been connected,
this could indicate a problem with a physical con-
nection, the network configuration or the Windows
Firewall,
Figure 5.3
Check Connections and Configurations
Check your cable connections and your TCP/IP set-
tings at both the PC and NLB 60E.
Check Windows Firewall
If this fault appears the first time you attempt to
upload subnets, and your PC has Windows XP with
SP2, your connection probably has been blocked by
the Windows Firewall.
When you first click on “Upload configuration”, a
Windows pop-up asks whether you want to con-
tinue blocking or allow network communication by
DeviceControl. Click on Unblock.
In some cases this pop-up window may be
hidden behind the main window. However,
you will see a “Windows Security Alert”
below in the system tray. Minimize the main
window or click on the Windows Security Alert in
the system tray to access the pop-up and click on
Unblock.
You can check to see if Windows Firewall is blocking
DeviceControl by accessing the Windows Security
Center in the Control Panel (Figure 5.4).
Set the Firewall to “On (recommended)” and click
on Windows Firewall in Manage Security Settings.
Click on the “Exceptions” tab and confirm that
DeviceControl Network Application is selected as
an exception.
