SQL server 2000 clustered on a WIndows Server 2003 cluster

Hi,

I have a query.

I am creating a SQL Server 2000 cluster on a Windows Server 2003 cluster, the question I have is:

Q1: Is it better to have the cluster nodes as Domain controllers and Additional Domain controllers or, Having them as domain members with a seperate domain controller is a better idea? what can be the benefits and disadvantages of both configurations?

Q2: What all issues can we face in both the scenarios?
