To maintain a consistent ___domain-based namespace across namespace servers, it is necessary for namespace servers to periodically poll Active Directory Domain Services (AD DS) to obtain the most current namespace data.
To optimize namespace polling
Use the following procedure to optimize how namespace polling occurs:
Click Start, point to Administrative Tools, and then click DFS Management.
In the console tree, under the Namespaces node, right-click a ___domain-based namespace, and then click Properties .
On the Advanced tab, select whether you want the namespace optimized for consistency or scalability.
- Choose Optimize for consistency if there are 16 or fewer namespace servers hosting the namespace.
- Choose Optimize for scalability if there are more than 16 namespace servers. This reduces the load on the Primary Domain Controller (PDC) Emulator, but increases the time required for changes to the namespace to replicate to all namespace servers. Until changes replicate to all servers, users might have an inconsistent view of the namespace.
Note
To set the namespace polling mode by using Windows PowerShell, use the Set-DfsnRoot EnableRootScalability cmdlet, which was introduced in Windows Server 2012.
