Issue the acurcl -start command from the administrator account or from an account that belongs to the administrators group. On Windows servers, it's best to specify acurcl -start with no options. Alternatively, you can click the Start button on the Windows graphical control panel's Services tab.
You can stop AcuConnect at any time by issuing the acurcl -kill command or by clicking Stop on the control panel's Services tab. See acurcl -kill for a discussion of the -kill command options.
