Issue
Returned when an attempt is made to set the MgmtMode property to lcaMgmtModePropagateConfigUpdates (0) without selecting a network interface.
Environment
LonMaker
NL220
Vista
LNS
Cause
After restoring an NL220 backup file and opening the project using the "Default" network interface, you may receive NS #135. Trying to re-open the network and manually chose the correct network interface, instead of "Default", the same the same error occurs.
Resolution
Open the smart channel window and then click on the IP channel, Attached, and Test All. This resolves the offline network interface. In the NL main window, chose Tools, Attached to Network, and the network status should return to ONNET.
If the Attached and Test All buttons are grayed out then try rebooting the server and connecting the NL220 database again. This may be due to all NIC ports being locked out by another program like Vista.
