Thanks Don,
I'll try resetting the default ip address on the DVR. I actually tried this but in all the 'learning" curve I've gone up so far on this equipment, I decided to just get her working first! The NIK manual says something about to going into the cameras and reseting their IP address; I'm assuming give them a static IP on my LAN. I'm assuming if everything has the same gateway and subnet, they'll be happy. I was trying to avoid this, but it appears that may be where it's headed! I'm new to networking, so this is a challenge. Thanks again for your responses.
Dave
