Consider the following scenario:
- You install the Distributed File System (DFS) Namespace service on a computer that is running Windows Server 2008 R2.
- The reparse points that are configured within the default namespace setting represent the corresponding DFS namespace folders on the server.
- You restart the server. During the startup process, the system time of the server is changed. For example, when you restart a virtual machine, the system time of the virtual machine is synchronized with the host computer during the startup process.
Note After the system time is changed, an event that contains the system time before and after the change is logged in the System log.
Users cannot access their DFS shares because of DFS links disappearing from root servers within every 30 minutes.
Note DFS Links and their associated reparse point might disappear at any time during the runtime of the server.
When the system time changes before the reparse points are validated, then the changed time of the DFS namespace folders may be earlier than the service startup time. Therefore, the issue that is described in the "Symptoms" section occurs.
Note After you apply this hotfix, the scavenging algorithm for reparse points no longer relies on time stamps for validation.
