I'm the assistant administrator, not the lead administrator I'm only 18 I asked my boss for the details and that's all he gave me.

All I know is we've got two "Windows 2000 Servers" and "Windows NT" and they all store backups, the "Windows NT" is currently the primary domain controller and DHCP Server, with two drive backups, the other Windows 2000 Server has 3 more in it, and the new one has one.
