ISA2004 SP3 Breaks Internet Access and RDP?

<![CDATA[ You have a computer that is running Microsoft Internet Security and Acceleration (ISA) Server 2004. You install ISA Server 2004 Service Pack 3 (SP3) on this computer either manually or from the Microsoft Update Web site.
If the ISA Server 2004 SP3 installation fails, a rollback operation is performed to restore the ISA Server components to their pre-update versions. However, after the rollback operation is complete, the Microsoft Firewall service does not start. Additionally, the following error messages are logged in the Application log:
