Issue

The sync interval value is different from the default, which is 1 hour (3600 seconds).

Impact

The DFS Namespace service may put more load than necessary on Active Directory Domain Services (AD DS), or be unable to recover from temporary failures to update AD DS.

Resolution

Use the Dfsutil command-line tool to set the sync interval on this namespace server to the default value of 1 hour.

To set the DFS Namespaces sync interval

  1. To open an elevated Command Prompt window, click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

  2. Type **Dfsutil server registry syncinterval set 3600 \\**servername, where servername is the name of the namespace server (the local server).
