Licenses needed for Backup Domain Controller?

I have a question for the licensing gurus here...

We have a DC running Windows 2000 Server. My supervisor has told me I can tentatively get a new Domain Controller soon (ours is 4 yrs old now). As such, i want to take another (newer) server and make it a backup (plug-n-play) domain controller.

My question is -- Do we need to purchase extra licenses for that server? OR, can we simply use a basic 5 CAL Server license until we need to promote the server to DC (if the new one crashes)? At that time, can we transfer the licenses from the original DC to the backup DC and go forward?

Please reply on the forum. THANKS!

Re: "..... until we need to promote the server to DC "

Let me first address the role of a second W2K server in your organization.

In Windows 2000 there is no "backup domain controller ".
DC's are multi-master, that is to say, the second one will add the redundancy you need and is not a backup in the sense of NT4 days but a fully operational DC that can be updated with new objects in the active directory and will replicate to your existing one.

With regard to licensing please refer to the following website where you will find this info.

1 - "You need a server license for each server within a Windows 2000 Server-based network "
2 - If you have per seat CAL's then you are ok there.
"Client computers are allowed access to any server within a Windows 2000 Server-based network, as long as each client machine is licensed with the appropriate Windows 2000 Server CAL. "
