ISA Server 2004 Configuration Guide 121
Configuring the Firewall Client
The Firewall client software enables you to control Internet access on a per user/group basis
for all Winsock (TCP or UDP) connections to the Internet. The Firewall client software
automatically sends user credentials in the background to the ISA Server 2004 firewall
machine. The user accounts can belong to the local SAM on the ISA Server 2004 firewall, or,
if the ISA Server 2004 and the clients belong to the same Windows domain, then the user
accounts can be stored in the Windows NT 4.0 SAM or Windows 2000/Windows Server 2003
Active Directory.
The firewall client software can be installed from the ISA Server 2004 machine or from
another machine on the network. If you wish to install the Firewall client software from the ISA
Server 2004 firewall computer, you must enable a System Policy Rule to allow access to the
share. A more secure configuration is to install the Firewall client share to a file server on the
Internal network.
In the following walkthrough, we will install the Firewall client share on the domain controller
computer and then install the Firewall client software on the Windows 2000 client computer.
Perform the following steps to install the Firewall client share on the domain controller
computer:
1. Insert the ISA Server 2004 CD-ROM into the CD drive on the domain controller. In the
autorun menu, click the Install ISA Server 2004 icon.
2. On the Welcome to the Installation Wizard for Microsoft ISA Server 2004 page, click
Next.
3. On the License Agreement page, select I accept the terms in the license agreement,
and click Next.
4. On the Customer Information page, enter your User name, Organization and Product
Serial Number. Click Next.
5. On the Setup Type page, select the Custom option.
6. On the Custom Setup page, click the Firewall Services entry and click the This feature
will not be available option. Click the ISA Server Management entry and click the This
feature will not be available option. Click the Firewall Client Installation Share entry
and click the This feature, and all subfeatures, will be installed on the local hard
drive. Click Next.
