I have used NIS for a few years now and on some past versions NIS has turned off Windows firewall and also disabled the windows security notifications so the windows will not keep telling me about the disabled firewall. I noticed in NIS 2010 that both Norton and windows firewall are turned on but do not seem to causing any issues with each other. I pretty much let NIS do all of it’s default settings so is this normal for NIS to keep Windows firewall turned on?
