I am trying to understand DFS and am trying to see if it is practical
for our environment. We currently have a 3 node cluster running NW6.5,
none of the nodes have edirectory or SLP installed on them. I am
trying to think of the implications if we move towards OES 2 sp 1 and
also begin using DFS and DST.

In our 3 node cluster will we need to have edirectory installed on all
three of these servers in order to have DFS?

I have read we also need to have SLP installed on them will they also
need to be DAs?

In reading about junctions I am somewhat confused on trustee rights.
For example I have read. "You must configure file system trustee rights
for users on the junction and the junction target location. For
visibility, users must have at least Read and File Scan rights on the
target location."
I am not sure I understand this. If I create a DFS Junction that points
to a volume\folder called soft\shared would all of my users then have
read rights to every sub folder in the shared folder?

In our current environment we are running into the 2TB drive limit for
our volumes. We need to break up our shared folder on our soft volume.
If I break this up using DFS and create a junction which points to
multiple folders on mulitple volumes. Won't I still run into the
problem where 32 bit operating systems have issues handling drives
greater than 2TB?

I have read through some information on what OES2 SP1 has to offer and I
know in previous versions AFP and Samba do not support DFS. Will this
be different with SP1?
