Just guessing here, but maybe the app doesn't have a reference point to locate the database dir from. Kinda like using ..\ with a unc path. There isn't a parent dir to navigate to (well, there is, but the computer doesn't know it), so it just errs out while ..\ with a drive letter works great. What if you create a shortcut with the working dir as \\f2_renal2\user1\apps? I don't know if that would work or not, but worth trying.
