This is also shoot-in-the-dark suggestion.Here are the three process that might need to be added for permissions in the Programs section.
NASNAVI2.EXE: NAS Naviator 2
NASSVC.EXE: NAS Power Management Service
NASSCHE.EXE: NAS Function Scheduling Application

Also if you read the link provided by Senior Member garywa it says make sure your ZoneAlarm firewall is configured to allow these ports: UDP 1900, TCP 2869.
Have no other suggestions other than this.
Have a nice Day
