system. For example, to determine Administrator privileges in Windows

2000, select Administrative Tools from Control panel, and then select Users

and Passwords. Use the Local Security Policy Setting tool to grant the

account Logon as a Service privilege.

NOTE: In earlier versions of the SI7 driver, the I/O Server was automatically logged

on with the FIXIOUser account. This logon was transparent to the user.

Once you re-register the driver, complete these steps:

[1] Start the Power Tool and make sure the Auto Start option is enabled. Refer to

Starting the I/O Driver from the Power Tool to learn how.

[2] Configure DCOM (Distributed Component Object Model). Refer to Setting

up Security When the Driver Runs as a Service to learn more.

[3] If your Human-Machine Interface (HMI) software is FIX or iFIX, start it.

When either program runs, it will start the SI7 Server as a service.

If your HMI is a third-party package, then complete these steps instead:

[a] Open the Services icon in Control Panel and change the SI7 Server

startup from Manual to Automatic.

[b] Start your HMI software.

You can reset the server to be a regular server process again by re-registering it:

SI7Drv REGSERVER

NOTE: Before you register the I/O Server to run as a regular server, you must

ensure that it is not currently running.

When registering the server this way, it will run, perform the necessary registration

work, and then exit. You can then start the server by using more conventional

methods such as starting FIX/iFIX, starting the Power Tool, or any client program

capable of communicating with the server.

NOTE: You cannot display the SI7 server window using Alt + Shift + S when the

server is running as a service.
