When attempting to open the Service File Viewer, the following error is seen and the application closes when clicking OK:
"No objects were returned from the configuration database"
To resolve this issue, the configuration file that is causing the problem will need to be renamed, which will be recreated automatically by Service File Viewer when it is launched again.
To perform this maintenance, open the following directory and rename the ServiceFilesViewer.config file by adding ".old" extension to the file.
"C:\Users\ServiceAccount\AppData\Roaming\Quest Software\Migration Manager\Exchange Data\Resource Kit"
Then simply open the Service File Viewer again and chose to add the agent hosts by right clicking "Agent Hosts -> Add Agent Host". You can chose to "Add specified Agent Host" to add specific hosts only, or simply choose "Add all Agent Hosts from configuration project"
