Delete DFS Namespace on 2003 servers for decommissioning.

We're decommissioning 2 * 2003 R2 servers that have a namespace set up in DFS Management. The namespace has never been used. Do we just open DFS management, right-click the namespace and delete?

Or do we delete the folders first on the servers and then delete Namespace? Or anything else we should be aware of?

Both servers are still online and running fine.

Have never done this before, hence the possibly daft/obvious questions.
