I can boot fine, so the nib folder is usable. It's just that it refuses to see the image repository, whether local or remote. It's a 10.6.x server. I have a 10.5.8 nib on there for my older Intel machines, and it works perfectly... BUT it's using NetRestore and not DS. I had to disable the DS nib to get the 10.5 to work. Again, boots but no images can be chosen. I have about 1,000 machines to do that are 10.5, and only 280 that are 10.6. My summer help has already cloned them over from external FW drives using NetRestore, so I am okay for a bit.
Soon or later I will figure it out. Actually have plans on killing the two current image servers and making new ones from scratch.
