Connecting to a Folder on a Different Partition Using AFP or SMB
For anyone who runs into this, the folks on the DeployStudio forums posted the answer:

afp://192.168.0.1/Volumes/NetRestore-Images/Repository


when connecting to a share, don't use the full path to the share point.  If the Share is named "Repository", then as far as your client is concerned, "Repository" is the root folder.  For example,

afp://192.168.0.1/Repository


or if you are sharing the NetRestore-Images folder,

afp://192.168.0.1/NetRestore-Images/Repository
