NETWORKING IN WINS 2000

I’M A NEW USER OF WINS 2000. ISET UP A NWETWORK OF COMPUTERS WITH WINDOWS 2000 SERVER. THE DOMAIN GROUP POLICY IS SHOWING AN ERROR.
AGAIN,HOW WILL I CONFIGURE A HARDISK IN ONE OF THE COMPUTERS ON THE NETWORK TO BACKUP ALL THE SYSTEMS IN ALL THE COMPUTERS.
FINALLY, I CONFIGURED THE DIALUP ON A COMPUTER TO BE CONNECTING TO THE NETWORK. IT CONNECTS, BUT I CAN’T ACCESS DATA IN THE NETWORK. I CONFIGURED THE RAS SERVER, AND CREATED AN ACCOUNT.
I WANT THE REPLY TO BE SENT TO
