Problem conclusion

• The Data Protection for Hyper-V data mover has been modified to
  not allow to store an encrypted password files on
  FAT/FAT32 volumes because these file systems don't support
  permissions.The client communication code has been changed
  to make sure all the used TCP/IP resources are closed gracefully
