with dir /o:n, you won't expect any delays for displaying the files and 
directories. ls -F will display filename and directory till the 
processing of the files are finished. If the directory has 2 or 3 
thousand files, you will feel that you are waiting forever.

Yes. Mapping the drive will work the trick. Just think if ls can work 
out without mapping drive

I am not sure why. ls xxxx_xx_200409292300.* will work in some machines.
without NTlfn package installed.
