Important Notes

• The functions "GetServiceDisplayName" or "SetServiceDisplayName" are only available on systems higher than Windows NT.
• If you change the logon of an service to a new user you have to grant him the Service Logon Privilege. Otherwise the service cannot be started by the user you have assigned.
• If you have any suggestions, comments or questions please mail me: mailto:rainer@speed-soft.de
• The functions StartService, StopService, PauseService and ContinueService uses a timeout of 30 seconds. This means the function must be executed within 30 seconds, otherwise the functions will return an error.
