Best Practices for Security and Group Policy with IEAK

Managing Enterprise Deployments with the Internet Explorer Administration Kit (IEAK)The Internet Explorer Administration Kit (IEAK) is a toolkit Microsoft provided to help IT professionals customize, configure, package, and deploy Internet Explorer builds across an organization. Although Internet Explorer has been largely superseded by modern browsers and Microsoft’s shift to Chromium-based Edge, many enterprises historically relied on IE and some legacy applications still require IE-mode or specific IE configurations. This article explains IEAK’s capabilities, walks through planning and customization, details packaging and deployment options, covers security and maintenance considerations, and offers troubleshooting tips for enterprise-scale rollouts.

What is IEAK and why it mattered to enterprises

IEAK enabled administrators to produce customized Internet Explorer installers and configuration packages tailored to corporate requirements. It bundled branding elements (logos, default home pages), preconfigured security and privacy settings, custom ActiveX controls, connection settings, and optional components. For enterprises, IEAK provided:

• A single, repeatable method to enforce consistent browser settings across many machines.
• Tools to reduce end-user support calls by preconfiguring proxy, security zones, and trusted sites.
• Packaging options compatible with software distribution systems (MSI, CAB, EXE).
• Ability to integrate custom toolbars, search providers, and localized resources.

Planning your deployment

Effective IEAK use begins with thorough planning:

• Inventory needs: identify applications and sites that require specific IE settings, ActiveX, or legacy behaviors.
• Decide the scope: global enterprise, departmental, or per-network segment builds. Multiple builds can be created for different user groups.
• Define baseline settings: security zone configurations, cookie/privacy policies, trusted sites list, proxy and connection defaults.
• Compatibility assessment: test legacy web apps against target IE version and consider IE Mode in Microsoft Edge where full IE is deprecated.
• Rollback and recovery: plan how to revert to defaults if the custom build causes issues.

Customization options in IEAK

IEAK exposed many customization points. Key areas:

• Branding and UI:

  • Replace splash screens, icons, product name, and default home page.
  • Include corporate help files and links to intranet resources.

• Security and privacy:

  • Predefine security zone levels (Internet, Local intranet, Trusted sites, Restricted sites).
  • Control ActiveX behavior, scripting, and file download policies.
  • Configure cookie handling and privacy settings.

• Connection and networking:

  • Preconfigure proxy servers, automatic configuration scripts (PAC), and dial-up/RAS settings.
  • Configure connection assistant and autodial behavior.

• Components and add-ons:

  • Include or suppress optional components (e.g., media features).
  • Package custom ActiveX controls, BHOs, or toolbars; set install flags and registry keys.

• Search, favorites, and feeds:

  • Add corporate search providers, prepopulate favorites/bookmarks, and subscribe to internal RSS feeds.

• Distribution packaging:

  • Build MSI, EXE, or CAB installer packages; create unattended installations with transforms (MST) or command-line switches.

Building and testing a custom IE package

1. Install IEAK on a management workstation.
2. Create a new project and select the base Internet Explorer version.
3. Apply branding, security settings, and any custom components. Use prescribed templates for consistency.
4. Configure installer options — choose MSI for Group Policy/SCCM-friendly deployment or EXE for simpler setups.
5. Generate the build and produce an administrative installation point if needed.
6. Test thoroughly in a controlled lab: verify first-run behavior, security zones, ActiveX behavior, proxy connectivity, and rollback. Use virtual machines to test different OS versions and patch levels.

Deployment strategies

• Group Policy / Active Directory: Deploy IEAK-built MSI via Group Policy for wide, controlled rollouts. Use transforms (MST) when small per-site differences are needed.
• System Center Configuration Manager (SCCM): Push MSI/EXE packages with deployment schedules, monitoring, and rollback options.
• Login scripts / software deployment tools: For smaller environments, use scripted installs with command-line switches for silent installs.
• Imaging: Integrate the custom IE into desktop images so new machines are provisioned with the corporate browser by default.
• Phased rollouts: Start with pilot groups (helpdesk, power users), gather telemetry, then expand.

Security, maintenance, and policy management

• Group Policy enforcement: IEAK settings can be mirrored or enforced via Group Policy Administrative Templates for ongoing management. Rely on central policies to prevent end-user changes where appropriate.
• Patching: Keep target Internet Explorer builds updated with security patches. Custom builds do not exempt systems from normal Windows Update processes.
• Legacy support vs. security: Weigh compatibility needs against security risks—ActiveX and older protocols can expose the environment. Use restricted sites and least-privilege principles.
• Transition planning: Map out migration to modern browsers and use Microsoft Edge’s IE Mode where feasible to eliminate dependence on IE while retaining legacy app compatibility.

Troubleshooting common issues

• Settings not applying: Check whether local Group Policies or later logon scripts override IEAK-applied registry keys. Use Resultant Set of Policy (rsop.msc) to diagnose.
• ActiveX/install fails: Verify signed controls, correct registry entries, and that security zones permit installation. Examine Event Viewer and Windows Installer logs.
• Proxy problems: Test PAC file accessibility and ensure automatic detection settings aren’t conflicting with static proxy entries.
• User profile vs. machine settings: Distinguish HKCU vs. HKLM registry locations — IEAK can set defaults but user policies or scripts may alter HKCU at logon.

When to use IEAK today

IEAK’s relevance has declined with Internet Explorer’s deprecation, but it remains useful when:

• Supporting legacy intranet apps requiring IE-specific behaviors.
• Preparing images for isolated or air-gapped networks where legacy browser versions are locked down.
• Creating consistent branding and default configurations for historical environments.
  For most modern deployments, prefer Microsoft Edge with IE Mode and modern management tools.

Example: Minimal IEAK workflow

1. Define required settings (trusted sites, proxy, homepage).
2. Create IEAK project and apply those settings.
3. Build MSI and test on VM.
4. Deploy to pilot group via Group Policy.
5. Monitor, collect feedback, then expand deployment.

Conclusion

IEAK was a powerful tool for enterprises to manage Internet Explorer at scale, enabling customized builds, centralized control, and simplified deployments. While modern browser strategies and Microsoft Edge’s IE Mode are preferable for current environments, understanding IEAK remains valuable where legacy dependencies persist. Proper planning, testing, and governance ensure a controlled rollout that minimizes security risk while meeting compatibility needs.
