Notes
jdstrand
this is only a problem if serving from a windows filesystem. This configuration is known to be broken. From changelog addition in svn r16454: Note: NTFS/FAT filesystem should not be published by the platforms other than Windows. Pathname interpretation (including short filename) is less than perfect.
