The Smart.OpcXml.Service.exe is the main binary of the Smart OPC XML Server. There are several commands shown:

If your service fails to start you should check the server log files for errors ("C:\Program Files\Smartsys Ltd\Smart OPC XML Server\Logs") and also should check windows application event logs for errors, because the fail may happen before intialziation of logging.

Remark: The user under the service is started must be elevated or to have access to the server folders to read required files and to write logs.

Remark: Stopping the service takes longer time than starting it. If you type "net stop SmartOpcXmlService" you may receive the following:

Usually this is not a problem, stopping really takes a longer time and if you check from services tab after few minutes you will see that the service really is stopped.

Remark: By default windows service is named SmartOpcXmlService, but it can be changed with the "-s" option of the install command, which we do not recommend, but if it is done then you must specify the service which to be uninstalled with the "-s" option of the uninstall command.

Remark: Display name of the service, which is shown in the services tab is different from the name of the service, used for starting and stopping with the "net" command.
