Multiple failures after you install Microsoft Security Update MS04-039 (890097)

SYMPTOMS

After you install the Microsoft Security Update MS04-039 on a computer that is running Microsoft Internet Security and Acceleration (ISA) Server 2000, you experience the following symptoms:

100% CPU utilization by the Web Proxy or Firewall service
Web Proxy or Firewall services do not start.
Web Proxy or Firewall services unexpectedly quit.

Additionally, you may not be able to install Microsoft Security Update MS04-039 on computers that are running Microsoft Windows 2000 Server Service Pack 3 (SP3).

CAUSE

This issue occurs because the original Microsoft Security Update MS04-039 package was built to run on computers with ISA Server 2000 Service Pack 2 (SP2). However, files that are required for the package to install correctly on ISA Server 2000 Service Pack 1 (SP1) are missing. Additionally, the installer package included a setting that limited installation to Windows 2000 Service Pack 4 (SP4) only.

RESOLUTION

On November 16, 2004, Microsoft re-released Microsoft Security Update MS04-039 to address these issues. To resolve this issue, install the re-released version of Microsoft Security Update MS04-039.
