Tony3d; That definitely sounds as if you either haven't installed a cow on your main system, or haven't added it to the render queue....or something in your configuration is blocking the functioning of the main system cow (an over-zealous firewall or security program can do that quite easily). You -will- notice that your main system render times will be a touch slower than a nearly equivalent remote node; the overhead of running Hypervue and a Cow at the same time (In a recent test of my almost rebuilt garden, the socket 754 Athlon 64 3000 with 1 gig DDR 266 was turning out frames faster than my main system, which is and socket 939 Athlon 64 3200+ with 2 gigs DDR 400; 7min 05sec average compared to 7min 34sec average).
