Removing the ISAPI Filter Plug-In

Detailed instructions for removing Websense filtering components are provided in the Removing Components. However, additional steps are required when you remove the ISAPI Filter plug-in from an ISA/TMG machine.

1.	Log on with local administrator privileges.

2.	Choose to uninstall a program:

Windows Server 2003: Go to Windows Control Panel > Add or Remove Programs.

Windows Server 2008 (x64): Go to Windows Control Panel > Control Panel Home > Uninstall a program (under Programs).

3.	Select Websense Web Security / Web Filter, and then click Change/Remove (Windows Server 2003) or Uninstall/Change (Windows Server 2008).

This launches the Websense uninstaller.

4.	On the Remove Components screen, select Filtering Plug-in and any other components to be removed, and then click Next.

5.	When the Stop Microsoft Firewall Service screen appears, stop the Microsoft Firewall service and then click Next.

 

Note  Leave the Websense uninstaller running as you stop the Microsoft Firewall service, and then return to the uninstaller to continue.

To stop the Firewall service, go to the Windows Services management console (Administrative Tools > Services). Right-click Microsoft Firewall (ISA Server) or Microsoft Forefront TMG Firewall (Forefront TMG), and then select Stop. When the service has stopped, return to the Websense installer and continue the uninstallation process.

 

Important  When the Firewall service is stopped, ISA/TMG goes into lockdown mode. Depending on your network configuration, network traffic may be stopped. Typically, the Firewall service must be stopped for only a few minutes.

6.	When the following message appears, start the Firewall service and then click OK:

The Websense ISAPI Filter has been unconfigured, you can now start the Microsoft Firewall Service.

 

Note  Leave the Websense uninstaller running as you start the Firewall service, and then return to the uninstaller to continue.

To start the Firewall service, go to the Windows Services management console (Administrative Tools > Services). Right-click Microsoft Firewall (ISA Server) or Microsoft Forefront TMG Firewall (Forefront TMG), and then select Start.

7.	On the Websense Software Removed screen, choose whether you want to restart now or later and then click Done.
