60. 60 Change in Domain

61. Controller configuration file DReplayController.config Changes location when you change domains Client configuration file DReplayClient.config Modify location in the configuration 61

62. Common issues Error DReplay The client ‘ClientServerName’ is not a registered distributed replay client. Make sure that the SQL Server Distributed Replay Client services is running on ‘ClientServerName’, and that the client is registered with the controller ‘localhost’. 62
