2. Installation and Configuration
2.1. ‘Log on as a Service’ privilege
The server runs as a Windows service. This means that it has no application window, it does not
appear on the taskbar and it cannot be started using an icon. However, it is able to run even when no
users have logged in and can automatically start on boot up without needing a user to log in.
Before installing the OPC Server, a user may be given privilege to start an application as a service.
Choose a user with Administrator privileges. If the service is to start in the local system account, then a
separate privileged user is not required.
Versions of the OPC Server before 102 operate as executable programs within the user login, and do
not need a service privilege. Starting and stopping these versions requires the program to be stopped
and restarted. The configuration functions described here are available from the server program itself.
2.1.1. Windows 2000 and XP
Click Start | (and Settings on 2000) Control Panel | Administrative Tools | Local Security Policy.
In XP, ‘Administrative Tools’ may also appear on the Start menu, or may have been disabled. To
enable this, right click on ‘Start’ and select Properties. In the ‘Start Menu’ tab, click Customize. In
the Advanced tab, scroll down the ‘Start menu items’ to the bottom and select to display ‘System
Administrative Tools’.
If the Control Panel is arranged in categories, in the Control Panel ‘Pick a category’ view, select
‘Performance and Maintenance’ and then Administrative Tools. Select ‘Local Security Policy’.
In ‘Local Security Settings’, select ‘Local Policies’. Select ‘User Rights Assignment’. Double-click
on ‘Log on as a service’. The Properties window shows the users that are allowed to start a service.
If the chosen user does not appear in the list, add the user by clicking ‘Add’ (2000) or ‘Add user or
group’ (XP). In XP, clicking ‘Advanced’ and ‘Find Now’ displays all available users.
