Odd behavior with QDLS folder

  This is confusing the **** out of me...

  I created a folder in QDLS to hold a single text file.  Other users need

  profile and password.  The only user/password that works is mine, it will
  not accept theirs.

  I checked the permissions through the iSeries Navigator.  I was listed as
  the owner on both the folder and the file.  I deleted the folder, created
  a new user specifically for the folder and file and then recreated the
  folder using this user.  This user profile is now the owner for both the
  folder and the file.  I also added all of the users to the permission list
  with "All" access.  Still, the only user profile and password that works
  to access the folder and file is mine.
  The PC is a Windows XP machine.
  Am I missing some step somewhere that will allow these users to access the
  folder/file?
