DFS Namespace service requires a long time to process a NetDfsRemove request if the specified DFS link does not exist in Windows Server 2008 R2 SP1
Article ID: 2512723 - View products that this article applies to.
Consider the following scenario:
For example, the DFS Namespace service stops responding for 30 minutes in a large DFS namespace when the service removes a DFS link that does not exist.
This issue occurs because the DFS Namespace service incorrectly triggers a DFS root synchronization process.
When the request for a link deletion targets a DFS link that does not exist in the namespace, a DFS root synchronization process starts. However, the DFS root synchronization process is a time-consuming process in a large DFS namespace. Therefore, the DFS Namespace service stops responding temporarily.
