UNC pathnames under Windows should work:  we use them daily in production.

What are the values for LISP-IMPLEMENTATION-VERSION for you?

Could you please refactor this to a reproducible test case outside of your code?

Try to see if something like

	(pathname “//fs2/14233205/path/to/some/file”)

fails and report the full stack trace (at least to the point that it resolves back
into Lisp calls).
