Windows 2000 Cluster server

I was looking over the Windows 2000 cluster step by step on Microsoft’s webpage. And it says you need a name resolution method such as Domain Naming System (DNS), Windows Internet Naming System (WINS), HOSTS, etc. Is that another way of saying you need active directory running??? I don’t see in a quick scan of that doc where it specifies that. We might need it for a application our company wants to run and out of around 20+ NT servers I only have on 2000 right now without active directory running. Can someone confirm whether I need active directory to run Windows 2000 server in a cluster??

Thanks
