AD Configuration and Disaster Recovery

We just did an upgrade from NT4 to 2003 Active Directory on a 350 node
network. It seemed to go rather smothly. We upgraded a fresh PDC
with Windows 2003 compatilbe hardware then added two new DCs. We then
demoted the upgrade server and it moved its roles to one of the other
new servers.

We now have two DCs running in interim mode with a couple of NT BDCs
Both of the new DCs are Global Catalog Servers. All the FSMO roles
were moved from the upgrade server to one of the new DCs. Both DCs
are DNS servers. The DNS servers are AD integrated.

I have a hard time understanding the Disaster Recovery information
that I have read so far. I thought oe of yo could net it out for me.

a. Is me config good fro disaster recovery e.g., all the FSMO roles on
on DC?

b. I think I know how to recover if I lose the DC that does not have
the FSMO roles. I could restore the system state and do an
unauthoritative restore, reboot and get averything I need from the
other DC via replication. I this accurate?

c.What to do if I lose the DC that has all the FSMO roles? Restore
the system state and do an authoritative restore?

Thanks
