Change the DNS cache duration of DFS Namespaces


In this article, I will explain how to change the DNS cache of a namespace.

By default, the DNS cache is 300 seconds or 5 minutes.

For example, during a server migration, it may be necessary to reduce the client cache.

Change the duration

Open the DFS Distributed File System Management console, right-click the name 1 and click Properties 2 .
DFS console

Go to the References tab 1 , change the cache duration 2 then click Apply 3 and OK 4 .
configure delay for cache

For the consideration of all the clients, it is necessary to wait for it to recontact the server which will be at most the old configured duration.
