## What you need to know

What decisions and permissions should be checked when creating a DFS namespace?

## Potentially affected

Administrators creating Windows Server DFS namespace roots.

## DSE recommendation

Have the file-service owner approve the namespace name and type.

## Article

## Source facts

A DFS namespace presents shared folders through a virtual hierarchy and a common access path. Microsoft offers a choice between a namespace associated with a domain and a standalone namespace during creation. Creation requires administrative or equivalent permissions on the selected computer. After creation, Microsoft directs administrators to restrict access to the namespace folder for both namespace types to protect the configuration. [Microsoft documentation](https://learn.microsoft.com/en-us/windows-server/storage/dfs-namespaces/create-a-dfs-namespace).

## Applicability

Identify the namespace server, desired path, namespace type, and intended administrators. Review any delegated permissions against the source before starting the wizard or adapting its PowerShell procedure.

## DSE recommendation

Have the file-service owner approve the namespace name and type. Record who can manage the root and the access restrictions to be applied immediately after creation. Keep the root design separate from the later choices of folder targets, referral preference, and replication membership.

## Verification

After creating the root in an approved environment, verify its type, hosting server, visible path, and management permissions. Test access with an intended user and an account outside the approved administrative group. Record the actual results before adding production folder targets or distributing the namespace path.
