User Folders

Hi All,

We are implementing DFS on Server 2K3 R2 accross 3 sites.

Site 1 - SBS 2003 R2 Premium Box + Server 2K3 R2 Box (File, Print + AD)
Site 2 - Server 2K3 R2 Box (File, Print + AD)
Site 3 - Server 2K3 R2 Box (File, Print + AD)

As many of the users move between the sites we would like to move all of the
users' folders to the DFS namespace and have it replicated to all three
sites.

Questions:

Am I going to have difficulty with telling SBS that user's home folders are
in a DFS namespace?

I would like to replicate all of the data to all of the servers while I have
them in the same room (pre-stage). Does anyone have ideas on how I am best
to set things up for prestaging and seeting up the DFS namespace while all
of the machines are connected and sitting on the same subnet?

Thanks in Advance
