USER NAME RESOLUTION
By default, SurfControl Web Filter resolves user names by issuing a NetBIOS query based on the MAC
address. Web Filter also includes the Enterprise User Monitor (EUM) utility for resolving user names in a
routed network. You can also use ISA Server to authenticate your users. See "ISA Server Authentication"
on page 12 for more details.
For more details on how EUM works, see "ISA Server Authentication" on page 12.
You can install EUM in one of the following ways:
• Install the EUM Agent on all your domain controllers.
• Install the EUM Login Agent on your network.
• Install NetWareEUM on your NDS Tree Servers.
INSTALLING THE EUM AGENT ON YOUR DOMAIN CONTROLLERS
Before proceeding with the EUM Agent installation, check the following:
• Make sure that the Web Filter server has a static IP address.
• Make sure you have administrative privileges on all domain controllers where the User Agent will be
installed.
• Make sure the Web Filter server is located in the correct domain.
• Make sure the firewall or router allows traffic through the provisioned port (default is 61695).
• For Windows NT domain controllers, make sure the security logs of the domain controllers are set to
overwrite events as needed.
• Try to perform this procedure when there are few or no users on the network, or when a forced log off
can be scheduled. This ensures the fastest, most accurate detection of users.
To install the EUM Agent on to your Domain Controllers:
1 From the Start menu, select Programs > SurfControl Web Filter > Enterprise User Monitoring >
Install Enterprise User Monitoring.
