Persistent UNC Drive Mount For Service Account

The solution was to create a small physcial partition to house directory symbolic links to the server locations.

C:\>mklink /?
Creates a symbolic link.

MKLINK [[/D] | [/H] | [/J]] Link Target

        /D      Creates a directory symbolic link.  Default is a file
                symbolic link.
        /H      Creates a hard link instead of a symbolic link.
        /J      Creates a Directory Junction.
        Link    specifies the new symbolic link name.
        Target  specifies the path (relative or absolute) that the new link
                refers to.

X:\>mklink /d X:\virtual_dir \\server_name\share\application_directory
