And more specific if 1 file gets edited on to seperate "servers" and repli= cated to a 3rd server=2C what happens then?=20 Of course such a write action "when it happens" is very very small chance. =20 =20 IF you want to use FreeBSD as a file server for a windows enviroment (with = ZFS) you can do 2 things 1) use ZFS and make a ISCSI -disk (istgt port for now) and connect the ISCS= I disk to a Virtual server with a windows "server" host=20 2) use ZFS + SAMBA=2C configure samba to use the AD information to give acc= ess (Single Sign On)=20 =20 The first one is the easiest & fastest way however it will cost you perform= ance compared with the second solution.=20 The most difficult is to have samba connecting to a AD enviroment without a= ny alterations on the windows machines/ad=20 and kerberos.
