Hello
Thanks for posting in Microsoft Community.
To replace the automatically generated self-signed certificate in Windows Admin Center (WAC) v2.4 with a new certificate that is already in the computer certificate store, you can follow these steps:
Prerequisites:
The new certificate is already in the Computer Certificate Store.
The new certificate should be the one used to encrypt HTTPS communication (that is, it should have Server Authentication enabled).
To replace the certificate:
- Open Windows Admin Center Configuration
Launch the Windows Admin Center app.
On the left side of the page, click Settings.
- Access Certificate Settings
In the Security section, select Certificates.
- Locate the current certificate
Under the Certificates section (referring to Server Certificates for HTTPS), you will see the self-signed certificate that is currently in use.
The details of the current certificate are displayed here.
- Replace the certificate
Click the Browse button to open the Certificate Store dialog box.
In the dialog box, select the Personal certificate store on your computer.
Locate and select the new certificate you want to use for Windows Admin Center. Please make sure that the selected certificate is valid and that server authentication is enabled.
- Apply the new certificate
After selecting the new certificate, confirm the selection and click OK or Apply to save the changes.
- Restart Windows Admin Center
After updating the certificate, you may need to restart the Windows Admin Center service for the changes to take effect:
Open a PowerShell window as an administrator.
Run the following command to restart the service:
Restart-Service -Name "wacs"
- Verify the new certificate
After restarting Windows Admin Center, open a browser and access Admin Center.
Check the HTTPS icon in the browser address bar to make sure the new certificate is in effect.
Click the HTTPS icon in the address bar to view the certificate details and confirm that the new certificate is in effect.
I hope the above information is helpful to you.
Best regards
