Hello, I am looking for some security advice regarding 'nmblookup'. I am a Mac user (G4, not Intel) running OS 10.3.9, Firefox browser. When I look up processor use, nmblookup is always running, using between 1.5% and 6% of the processing power. My question is whether this indicates some sort of spyware is operating on my system, or simply a normal background daemon working normal processes? Thanks in advance. Rick Glanvill
