You'll note that this path is over 255 characters (260?). You need to disable "path parsing" by starting the URL with \\?\ and you may need to use the "Unicode" APIs (not like you have any control over that). Which means you might not be able to get Perl and File::Find to work on such long paths.

So how about making the path shorter by having "net use" (or Win32::NetResource) assign a drive letter to that network drive. You could even use the "subst" command to remove the "XYZ Production Support" from the path length by assigning a drive letter to that subdirectory.
