You should consider the fact that if you have a Windows Server 2003 Enterprise licence then you are legaly entitled to install upto 4 instances of the OS on a virtualised platform.

So if your hardware is upto it.... Convert to a VMWARE/HYPERV system and install 2 DC's. Ideally you could go to running each DC on a different RAID/SAN/NAS device and you instantly added a lot of redundancy.

Running AD with only one DC is a nightmare waiting to happen. ANY fault with your DC and you bring your network to a grinding halt possibly.

As to what to backup? A FULL backup of your DC WITH a system state backup as well is the only reliable backup you should rely on.  And of course you will need to be testing the restore process before you actually need it.

Yes, restoring only System state on other Windows installation, DC runs again with same configuration, but is very recommended add another DC.

You shall restore the system state, but a domain shall need to be fault-tolerant so you need atleast to have 2 Domain Controllers , 2 DNS and if using DHCP 2 dhcps also. Then balance the roles on the DCs.

that´s my suggestion.

If the Domain controller is the only server on the network i would highly recommend investing in software such as symantec system recovery and a NAS device. Take Full images and incremental snapshots of all drives throughout the day and in the event of a failure, you could restore the image in a matter of hours.. plus it covers you in the event of a total system failure as you can bare metal restore your DC. I recovered a server in less than 15 minutes this way!! Its a fantastic tool to have.
