The configuration file or the command line has a duplicate parameter.
Any action to correct the problem should be performed on that computer. An option was used more than once in your command or in the configuration file. An option can be used only once in a command and once in the configuration file. If an option is typed from the command line, it overrides the value in the configuration file.
Do not type the same option twice in a command. Be sure not to use different abbreviations that can specify the same option, such as wrkserv and wrkservices. If the error was not caused by a command, check the configuration file for duplicate options.
