  Why are you using SMB, there are a ton of better and more secure options.

  Then how about you list some...

  Try NFS or iSCSI

  ISCSI is not useable as it is no real disk and Windows will want to format it after creation - but i'll have a look at NFS
  EDIT: NFS is out as well, cannot mount folders which already have other mounts in it (shown as empty on the client)

  @William: Are you trying to build a hierarchical structure? A "master" share that the client will use (as example a drive labeled N: on a Windows client), and lower-level shares are inside this one (as example: N:\share1 is the first share, N:\share2 the second, N:\share3 the third...). This is done with the dfs management console on a Windows domain controller. It works pretty well, it also can mirror data between shares automatically, when required.

  Yes, exactly!
  Any special software or network setup required to use a 2008 R2 Standard as Domain controller?

  If I understand tour question, then no special software is needed.

  Install win2008 and add the roles after.

  As MikHo said, no special software is needed, but each computer joined to the domain should be licensed with the usual CAL. The step-by step guide for Windows 2008 is here: http://technet.microsoft.com/en-us/library/cc732863(v=ws.10).aspx ; 2008R2 is basically the same, while Windows2012 is different. The namespace could be created for non-domain joined computers if you don't require replication, but I never tried this configuration.

  As this requires 2008 Domaincontroller (which is damn expensive) i settled for a different way.

  I kept the 2 shares per NAS and use NTFS junctions and a local script to symlink all of the second HDD array to the first one (NTFS junctions, unlike symlinks, also work over a shared directory as they are locally processed and redirected to the second HDD).
  -> 1 share per node

  For my 'special' nas that uses 2 nodes i used iSCS Target on the second one to expose the HDDs, mount them on the first one (as NTFS junctions can only be created on local volumes, not remote mounted) via iSCSI initiator and they behave like local disks, then did junctions as above.

  Does not solve my initial problem but i simply circumvented the share that 'reshares' on this Samba server

  Edith: more comments in the scripts

  Heres the scripts (bash, requires cygwin) for the interested:

  Makes new junctions, just cron it, self detection if it already exists

  #!/bin/bash
  #####
  #This script is made for Cygwin. It will NOT RUN on a linux system and likely cause damage.
  #william AT william DOT si
  #Case was a server running 4x 2TB in Raid1 and 2 iSCSI mounts also with 2TB each
  #these hold dirs than can simply be symlinked to one main dir
  #so this script goes through all targets and symlinks as required
  
  #full path, must be cygwin readable
  sourcedrive1="/cygdrive/e/"
  targetdrive="/cygdrive/d/"
  #####
  #convert /cygdrive syntax to windows
  winsrc=$(echo $sourcedrive1 | sed -e "s/\/cygdrive\///" -e "s/\///")
  wintrg=$(echo $targetdrive | sed -e "s/\/cygdrive\///" -e "s/\///")
  #get list, exclude some windows default items
  for i in $(ls -1 $sourcedrive1 | egrep -v '(RECYCLE.BIN|System Volume Information)'); do
                  #check if dir already exists, i use -d as it returns 0 if the junction is broken/dead unlike -x and it will automatically be recreated then
                  if [ -d $targetdrive$i ]; then
                          #on cygwin, an if block requires content, so we echo some bs here
                          echo "$i already existing - skipping"
                  else
                          #sleep to avoid disk IO raping
                          sleep 0.05
                          #mklink is a function of cmd.exe, not a binary
                          cmd.exe /c "mklink /J $wintrg:\\$i $winsrc:\\$i"
                  fi
  done
  

  Checks existing junctions and echoes recommendations for removals

  #!/bin/bash
  #####
  #This script is made for Cygwin. It will NOT RUN on a linux system and likely cause damage.
  #check for dead NTFS junctions (due to move of files etc.) and delete them
  target="/cygdrive/d/"
  ###
  #DO NEVER USE rm -r OR THE RECURSIVE ACTION WILL WIPE THE DIRECTORY CONTENT
  ###
  #get list, exclude some windows default items
  for i in $(ls -1 $target | egrep -v '(RECYCLE.BIN|System Volume Information)'); do
                  #check if target exists, -d defaults to 0 if the junction is dead and 1 if it works (as a junction without target is a simple file, with it the overlay is a folder)
                  if [ -d $target/$i ]; then
                          #content required by cygwin, false should not do anything
                          false
                  else
                          echo "$i is dead"
                          #remove the echo if you want the script to work full automatic
                          echo "rm $target$1"
                  fi
  done

  Note: I upgraded to 2012 now and use Storage spaces + DFS (which somehow works on 2012 Standard as well).

  Works fine but rather slow in RAID5 (slow CPU), biggest plus is data deduplication and bitlocker encryption.
