ViewStor is a built-in software service that provides the Point-in-Time Explorer feature of this software. It uses the Microsoft WebClient service to access archives. If the WebClient service is not running, you will not be able to use Point-in-Time Explorer to explore for files. In this case, you must restore all files from a restore point by clicking the Restore button.


On Windows Vista, Windows 7, and Windows Server 2008 and newer platforms, ViewStor is configured to listen on port 8500. On these platforms, you can change the ViewStor listening port by checking the box to override the default listening port, then selecting a new port number. You will be prompted to restart the ViewStor service for the new setting to take effect.


Note: On Windows Server 2003, the ViewStor service requires port 80 to explore restore points. Only restore functions are available if the ViewStor listening port is not port 80.


To change the ViewStor settings, open the ViewStor tab of the Archive Manager properties page.
