I know this is closed, but this doesn't resolve the issue. The problem occurs when jupyter_notebook_config.py is modified. When line 202 is given a value other than the default and uncommented, notebook fails to resolve. You are left with 404 errors. When the line is re-commented, the notebook will happily run, but only in the default directory.

I solved the issue. The default directory is apparently not allowed to be set to a base drive, it must be a folder within the drive. As such, "F:/" does not resolve, but "F:/Folder/" does work correctly.
