+# IISADMPWD – Active Directory Password Change Portal for Modern Windows Server
+
+This project restores the classic **IISADMPWD password change functionality** on modern Windows Server versions (2008/2012/2016/2019/2022+) and provides a slightly modernized UI.
+
+It allows domain users to **change their Active Directory password through a web portal**.
+
+Microsoft deprecated this feature after **IIS 6**, so it is no longer available in clean Windows Server installations. This repository provides the required files and instructions to restore the functionality.
+
+## Features
+
+- Active Directory password change via web UI
+- Compatible with modern Windows Server versions
+- Works behind reverse proxies such as Caddy, Nginx, and Traefik
+- Updated UI with a more modern look
+- Lightweight, with no external dependencies
+- No visible internal IIS path required for end users
+
+## Architecture Example
+
+```text
+User
+ │
+ ▼
+https://password.example.com
+ │
+ ▼
+Reverse Proxy (Caddy / Nginx / Traefik)
+ │
+ ▼
+IIS Server
+/reset-password
+```
+
+External users only see:
+
+```text
+https://password.example.com
+```
+
+The internal IIS path remains hidden.
+
+## Installation
+
+### 1. Copy the files
+
+Copy the repository contents to your IIS server:
+
+```text
+C:\inetpub\wwwroot\reset-password
+```
+
+The folder structure should look similar to:
+
+```text
+reset-password
+ ├─ aexp2.htr
+ ├─ aexp2b.htr
+ ├─ aexp3.htr
+ ├─ aexp4b.asp
+ ├─ achg.asp
+ ├─ achg.htr
+ ├─ iisadmpwd.htr
+ └─ iispwchg.dll
+```
+
+### 2. Register the password change DLL
+
+Open an **elevated command prompt** and run:
+
+```cmd
+regsvr32 C:\inetpub\wwwroot\reset-password\iispwchg.dll
+```
+
+You should receive a success message similar to:
+
+```text
+DllRegisterServer in iispwchg.dll succeeded
+```
+
+### 3. Enable password change functionality
+
+Navigate to the IIS AdminScripts directory:
+
+```cmd
+cd C:\Inetpub\Adminscripts
+```
+
+Then run:
+
+```cmd
+cscript adsutil.vbs set w3svc/passwordchangeflags 0
+```
+
+#### PasswordChangeFlags values
+
+| Value | Description |
+|------:|-------------|
+| 0 | Default – password changes enabled |
+| 1 | Allow password changes without SSL |
+| 2 | Disable password change |
+| 4 | Disable password expiration notifications |
+
+Recommended value:
+
+```text
+0
+```
+
+### 4. Enable Classic ASP
+
+This application requires **Classic ASP**.
+
+Install the feature using PowerShell:
+
+```powershell
+Install-WindowsFeature Web-ASP
+```
+
+Or via **Server Manager**:
+
+```text
+Web Server
+ → Application Development
+ → Classic ASP
+```
+
+### 5. Create the IIS application
+
+Open **IIS Manager** and navigate to:
+
+```text
+Sites
+ → Default Web Site
+```
+
+Right click **Default Web Site** and select **Add Application**.
+
+Use the following values:
+
+**Alias**
+
+```text
+reset-password
+```
+
+**Physical Path**
+
+```text
+C:\inetpub\wwwroot\reset-password
+```
+
+**Application Pool**
+
+```text
+DefaultAppPool
+```
+
+Click **OK**.
+
+### 6. Restart IIS
+
+```cmd
+iisreset
+```
+
+## Local Test
+
+Open one of the following URLs in your browser:
+
+```text
+http://SERVER/reset-password
+```
+
+or
+
+```text
+http://SERVER/reset-password/aexp4b.asp
+```
+
+## Reverse Proxy Example (Caddy)
+
+This example exposes the portal at:
+
+```text
+https://password.example.com
+```
+
+while internally running under:
+
+```text
+/reset-password
+```
+
+Example Caddy configuration:
+
+```caddy
+password.example.com {
+	handle {
+		rewrite * /reset-password{uri}
+
+		reverse_proxy <ip-address>:80 {
+			header_up Host {host}
+			header_up X-Forwarded-Host {host}
+			header_up X-Forwarded-Proto https
+			header_up X-Forwarded-Port 443
+			header_up X-Forwarded-For {remote_host}
+		}
+	}
+}
+```
+
+Users only access:
+
+```text
+https://password.example.com
+```
+
+## Security Notes
+
+- Always place the portal behind **HTTPS**
+- Prefer a reverse proxy with **TLS termination**
+- Consider restricting access to **internal networks or VPN**
+- Do not expose the portal publicly without proper access controls
+
+## Supported Windows Versions
+
+Tested with:
+
+- Windows Server 2012
+- Windows Server 2016
+- Windows Server 2019
+- Windows Server 2022
