The EUM Agent on the domain controller will wait ten minutes before checking for any changes made in
the scua.ini file. The frequency of this can be changed by altering a registry setting on individual domain
controllers. To change this value, perform the following:
1 On the domain controller, launch the Windows registry.
2 Depending on your operating system, navigate to one of the following keys:
• Windows 2000 and 2003
HKLM\SOFTWARE\JSB\SurfControl SubAuth\ConfigReRead
• Windows NT
HKLM\SOFTWARE\JSB\SurfControl EUM\ConfigReReadd
3 Edit the ConfigReRead value to the desired amount in seconds. By default, this value is set to 600
seconds (10 minutes).
There are two ways to add domain controllers or ignored users to the EUM Agent configuration:
• Use the EUM Installation Wizard.
• Manually edit the scua.ini file on each domain controller.
Using the EUM installation wizard. To start the wizard, follow the instructions in the Installing the
EUM Agent on your domain controllers section. The installation wizard will automatically detect if the EUM
Agent is already installed, and you can select additional domain controllers and/or ignored users to add to
your existing EUM configuration.
Manually edit the scua.ini file. By default, the scua.ini file contains the host name and listening port
number of the Web Filter server from which you initially installed the EUM Agent, and any ignored users
you specified during the installation. You can add extra Web Filter servers to the file, if you want user login
information to be returned from your domain controllers to multiple Web Filter servers. Below is an
example of the scua.ini file:
[surfCONTROL_Services]
192.168.4.125=61695
192.168.4.119=61695
192.168.4.215=61695
[ignored_users]
domain\user1.test=1
domain\user2.test=1
domain\user3.test=1
To manually edit the file:
1 On the domain controller, open the c:\Surfcontrol User Agent\scua.ini file.
