a pdc and something far from it

[Mailing Manager]

Hi all,
        i'm going to find a solution to this problem:
Central headquarter with a samba server configured as a PDC, with
netlogon etc etc.
External office connected via leased line with a bdc (or something else)
taha will cache only the files (homes, profiles) and authorized the
clients (smbpasswd centrlly on the pdc).
Waht kind of configuration i will have on the external office?? I have
the pdc working well, but i'm afraid that when a user with a big
profiles will logogn form the external offices , everytime the nt
clients will copy the profiles and other files form th ecentral
samba...this will be very bad!!
Someone have encountered a similar operating situation?? what can yi do
for minimze the necessity to copy files from one server to th eother and
let the sambas works well with the profiles and homes files??

                                thanks
