Configuration 25

Configuration Restart the services on all the servers NET STOP “SQL Server Distribute Replay Controller” NET START “SQL Server Distribute Replay Controller” NET STOP “SQL Server Distributed Replay Client” NET START “SQL Server Distributed Replay Client” On each server that has the services installed 26

Configuration The Rest of the Story

Configuration Check for errors C:\Program Files (x86)\Microsoft SQL Server\110\Tools\DReplayClient\Log Failed to connect controller with error code 0x Error code 0x means “Access is denied” 28

60 Change in Domain

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

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
