Hello Myles,
I have tried this solution too. But no changes!!. Network Connections comes under "General Tab"
Window -> Preferences -> General-> Network Connections -> Active Provider.
I have contacted with SAP Dev team. They its not a major issue. My database will work fine , but I will be unable to stop/start the instance from HANA Studio.
Guess I will have to go with that!!!..No other options left..I wanted to go in depth of this problem.
