I'm had troubles with this property (
http://zone.ni.com/reference/en-XX/help/371618F-01/lvdscprop/sv_network_on_scan/) . I'm developing a system who creates all variables programmatically and i read about the properties to setup them. In the manual the Default value for this property is FALSE, but in real life the Default value is TRUE and works fine with the default value.
When i try to put the Default value of the manual i had trouble, all variable was frozen and and I don't know why this happened. So i created a new variable through Distributed System Manager and programmatically i check all properties thats not showed in Distibuted System and I saw this property have a different default value.
