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