IIS Troubleshooting

A collection of scripts to troubleshoot common IIS permissions and configuration issues on Windows.

Scripts

File	Description
troubleshoot-iis.ps1	PowerShell script with colored output, error handling, and folder validation
troubleshoot-iis.bat	Batch script for Windows Command Prompt

What It Does

1. Check IIS version — Queries the registry to display the installed IIS version.
2. Take ownership — Recursively takes ownership of ScriptLog folders (public/log, public/cache, public/themes, admin/plugins).
3. Grant Administrator full control — Applies (OI)(CI)F permissions to Administrators.
4. Remove read-only attribute — Strips the read-only flag recursively.
5. Grant AppPool modify access — Gives (OI)(CI)M permissions to IIS AppPool\Scriptlog.
6. Restart IIS — Runs iisreset to apply all changes.

Usage

PowerShell (Run as Administrator)

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\troubleshoot-iis.ps1

Command Prompt (Run as Administrator)

troubleshoot-iis.bat

Note: Both scripts must be run as Administrator for takeown, icacls, and iisreset to work.

Requirements

• Windows Server / Windows 10+
• IIS installed with ScriptLog deployed at C:\inetpub\wwwroot\scriptlog
• Administrator privileges
