05 Oct 2013 23:51

If you are renewing your SSL certificate running on Microsoft Internet Information Services (IIS) 7, you will need to perform some simple tasks from your IIS 7 web server before placing an order to renew your expring SSL certificatate.

Generate Renewal Certificate Request File (CSR)

  1. Open the Internet Information Services (IIS) Manager. From the Start button select Programs > Administrative Tools > Internet Information Services Manager.
  2. In the IIS Manager, select the main server node on the top left under Connections
  3. In the Features pane (the middle pane), double-click the Server Certificates option located under the IIS or Security heading (depending on your current group-by view).
  4. You will be presented with a list of SSL Server Certificates currently installed. Select and highlight the expiring certificate that you want to renew. Check the certificate's Expiry Date to make sure you have selected the correct one. 
  5. From the Actions pane on the right, select Renew. From the Renew an existing certificate dialog box choose the second option, Create a renewal certificate request. Click Next.
  6. Specify a file name for the renewal certificate request. It doesn't matter what you call it or where you save it as long as you know where to find it. You'll need it in the next step. We recommend calling it certreq.txt.
  7. Click Finish to complete the certificate request (CSR) wizard.
  8. Now, from a simple text editor such as Notepad (do not use Word), open the CSR file you just created at c:\certreq.txt (your path/filename may be different). You will need to copy-and-paste the contents of this file, including the top and bottom lines, into the relevant box during the online order process.
