Creating the Certificate Signing Request file in Microsoft IIS 5 :

The first step you will need to perform to get a server certificate is creating the Certificate Signing Request file. To generate a new Certificate Signing Request, perform the following steps:

1. Open the Internet Services Manager (or your custom MMC containing the IIS snap-in).
2. Browse to the site where you want to enable secure communications.
3. Right-click the friendly name of the site and go to properties.
4. Click the Directory Security tab.
5. Under the Secure Communications section, click Server Certificate.
6. This starts the new Web Server Certificate Wizard.
7. Click Next.
8. Choose the Create a New Certificate option and click Next (there should be a slight pause before the next screen appears).
9. Choose the Prepare a New Request but Send it Later option and click Next.
10. Choose a Friendly Name for the site (this can be anything you want it to be, for example, the friendly name of the site in the MMC, or the name of the customer the Web site belongs to).
11. Choose the bit length of the key you want to use and whether you want to use SGC (Server Gated Cryptography), and then click Next.
12. Input your Organization (O) and your Organizational Unit (OU). Click Next when complete.
13. Input the common name (CN) for your site. This should should reflect your webserver dns name.
14. Click on Next
15. Input you Country/Region, City, and State. It is very important that you do not abbreviate the names of the state or city. When complete, click Next.
16. Choose a name for the Certificate Signing Request file you are about to create. This file will contain all the information you created here, as well as your public key for your site. You can browse the file name if you want. This creates a .txt file when you are complete. The default name for the file is Certreq.txt. When you have finished this step, click Next.
17. You will now be presented with a summary screen of all the information you entered. Make sure all this information is correct, and then click Next.
18. You have now created your Certificate Signing Request file.
