Hello Scott,
If you have project files and datasets located on different network drives, please consider mounting them though the same network "root" path: instead of having //STORAGE/ , //DATA/ and, for example, //PROJECTS/ I suggest the following:
//STORAGE/
//STORAGE/DATA/
//STORAGE/PROJECTS/
In this case you do not need to use absolute paths, instead you can keep relative paths (default) option and use //STORAGE/ as a root path, when starting the processing nodes and in the Network tab of the client machine.
