This article will detail the steps for obtaining an SSL on a Windows IIS 10 Server server using TrustCor Premium DV Certificates.

1. Purchase trustcor from No-IP.

How to Purchase and Configure a TrustCor Premium DV SSL

2. Generate a CSR using Internet Information Services (IIS) Manager.

  • In Internet Information Services (IIS) Manager, in the Connections menu tree (left pane), locate and click the server name.
  • On the server name Home page (center pane), in the IIS section, double-click Server Certificates.


  • In the Actions menu (right pane), click the Create Certificate Request link.


  • This will open a wizard for Request Certificates, fill out the information, using your domain for the Common Name field. When finished, click Next.


  • This will take you to the Cryptographic Service Provider Properties page.
  • From the Provider dropdown, choose “Microsoft RSA SChannel Cryptographic Provider”.
  • Then, from the Bit Length dropdown, choose “2048”.
  • Click Next when completed.


  • In the final step, you will be taken to the File Name page. Be sure to note the name you provide and where it is being saved.

If you do not choose a file location, your CSR will end up in C:\Windows\System32.


Add CSR to No-IP

3. Now that the CSR has been created, you can open this with a TXT editor to copy and paste this into your No-IP account.

Copy the CSR, including everything from




4. From your No-IP account, Click My Services at the left, then SSL Certificates.

Locate the TrustCor Premium DV and click the Add CSR button.


5. Here, you will choose your server type from the drop down menu, paste the CSR we just copied, then click the green “Add CSR” button to continue.


6. You will now see the section called “SSL Contact Information“.

Fill in the information required. The City, State and Country will be auto-filled from the information generated in the CSR you created. Click the green Confirm button when finished.


7. Finally, you will see the section called “DNS Verification Record”.

If your domain is registered with us and you have Plus Managed DNS, we will add the DNS Verification TXT record automatically.

If you are an Enhanced user with us, you will need to copy and paste the DNS Verification TXT record to your DNS Records manually.

If your domain is not registered with No-IP, you will need to copy and paste the DNS Verification TXT record to your DNS Records manually at your current DNS provider.

Click the Continue button once you have reviewed and/or copied this information.


8. Wait for Verification. TrustCor will search for the TXT record you have added to your domain.

This typically happens within the hour, after the TXT record is added and propagated. Until then, the Status will remain in Pending Verification.


After about 30 minutes, TrustCor will verify the TXT record and the Status will change to Active.

9. Download the signed-cert from the No-IP UI.

From your No-IP account, click My Services at the left, then SSL Records. Find your TrustCor Premium DV and click the Download button.


10. Here, use the dropdown menu to select the file type and click the Download button to obtain the file.


11. You will take this Certification file and install this onto the same machine you generated the CSR from,
by using the Internet Information Services (IIS) Manager. This is usually completed using the IIS “Complete Certificate Request” feature.

You may need to make further configurations to the IIS, such as assigning the SSL using the Binding program of the server. While we do not support this level of server configuration, you can find many useful guides on the internet, such as this one:

You have now installed the SSL on your IIS server.
