Thanks,
I've used DS in the past, was just hoping to use the Apple Software. I was finally able to get this going. Just posting now for anyone else's sake.
I have a partitioned HD on my server. I created the partition for storage. I turned on cache service, and have the cached files located in the partition. I turned on the netinstall service, and pointed it at the same Library folder that was created for cache server.
The issue is this, Cache server's permissions to the Library and subsequent folders are incorrect for use with netinstall. I needed to add Root as the owner, and wheel as the group instead of whatever Cache server put in by default.
That was essentially it...
Now if only I can get this image to multicast... I can't connect multiple clients to the server...
