I think you want to set vc-ignore-dir-regexp (to the same value as
locate-dominating-stop-dir-regexp) for this.

Backslashes don't escape (at the regexp level) inside square brackets,
[\\/] just matches / or \. If it was written [/\\] it would mean the
same.

Perhaps translating to rx syntax would make it clearer:

(sequence string-start
          (or
           (sequence
            (any "/" "\\")
            (any "/" "\\")
            (one-or-more
             (not
              (any "/" "\\")))
            (any "/" "\\"))
           (sequence "/"
                     (or "net" "afs" "...")
                     "/"))
          string-end)
