How to make a password reset website for AD users Windows Server 2012r2

In the past, you could use the IISADMPWD to make a website for your Active Directory users to change passwords.  That functionally is no more with Server 2012 and higher.  At the time – we didn’t have the funds to buy a password reset solution for our department so I found another way.  Using remote desktop services – RD Web Access you can accomplish the same thing for free.  Below is my tutorial on how to do this.

Windows Server Active Directory users password change website:

DPM recover system drive disk space

How to recover space on your SCCM DPM 2012 server system C drive.

Open file explorer and browse to
C:\Program Files\Microsoft System Center 2012 R2\DPM\DPM\Temp
Here you might see many .errlog files.

You can safely delete these .errlog files but first you need to investigate the most recent ones and take the appropriate actions.  If you need to recover space immediately then copy the most recent few logs to an alternate location and then you delete all of them on the DPM server.

How to setup password reset website Server 2012

If you want to have a password reset website for your users but don’t want to purchase a 3rd party solution – you can still do this using Microsoft 2012 Server.

How to setup a password reset website using Server 2012 RD Web

Choose a server to install this role. For my environment, I chose to use the print server.

1. Install RD Web Access from the Remote Desktop Services. Remote desktop to your server (I’m installing this on my print server) and open Server Manager.  Add Roles and Features – Next – Remote Desktop Services installation – Next.

2. Choose Standard deployment – Next.
Choose Session-based desktop deployment – Next.
On Role Services – Choose Next.

3. On Specify RD Connection Broker server – select your server – add it and choose Next.

4. On Specify RD Web Access server – Place a checkmark in the Install the RD Web Access role service and click Next.

5. On Specify RD Session Host servers – select your server – add it and choose Next.

6. Confirm your selections – place check mark in Restart the server and click Deploy.


7. When the server finishes restarting – Launch Server Manager and wait for it to complete. Once it completes, you will see a pop up regarding licensing mode.


In my experience, as long as you do not install the RD Licensing then the RD password reset website that we are going to configure next will continue to work after the 119 days.

Setting up the website and related configurations for domain password reset

8. Launch Server Manager – Tools – IIS Manager
Expand Sites – Default Website – RDWeb – Pages – then in the middle pane – open Application Settings.

9. Double click PasswordChangeEnabled and switch the value to true and click OK.

Now your Password reset website is enabled and you can test it by going to this address on your server:

When someone needs to change their password I now send them this link and they can do it remotely.
