Certificate Signing Request (CSR) Generation Instructions for Microsoft IIS 6.0

This document provides instructions for generating a Certificate Signing Request (CSR) for Microsoft IIS 6.0. If you are unable to use these instructions for your server, Symantec recommends that you contact Microsoft. 

NOTE: To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file and generate a new one, your SSL Certificate will no longer match. You will have to replace the certificate then.

NOTE: If you are renewing a previous certificate with IIS that has a 1024 bit key length, refer to the following solution ID for steps on creating a new CSR with a 2048 bit length without removing the previous certificate SO1552.

To generate the Certificate Signing Request (CSR) file, perform following steps:

NOTE: All certificates that will expire after October, 2013 must have a 2048 bit key size.

  1. Under Administrative Tools, open Internet Services Manager.
  2. Open the Properties window by right-clicking on the name of the Web site you wish to secure.

  3. Click the Directory Security tab.
  4. Click Server Certificate in the Secure communications section.
    If you have not used this option before the Edit button will not be active. 

  5. Select Create a new certificate 

  6. Select Prepare the request now, but send it later. Symantec only accepts CSR’s through
    the enrollment process forms. We do not accept CSR's via email. 

  7. Provide the friendly name for this certificate.  This will help you identify the certificate if
    multiple certificates are installed.  For the bit length, specify 2048.  Click Next.

  8. Provide the Organization and the Organizational Unit information and click Next.

    Organization (O): If your company or department has an &, @, or any other symbol using the
    shift key in its name, you must spell out the symbol or omit it to enroll. Example: XYZ Corporation
    Organizational Unit (OU): This field is the name of the department or organization unit making the request. 
  9. Provide the Common Name and click Next.

    Common Name (CN): The Common Name is the Host + Domain Name. It looks like "www.company.com" or "company.com".
    Symantec certificates can only be used on Web servers using the Common Name specified during enrollment.
    For example, a certificate for the domain "domain.com" will receive a warning if accessing a site named "www.domain.com"
    or "secure.domain.com", because "www.domain.com" and "secure.domain.com" are different from "domain.com".
  10. Provide the Geographical Information for your Organization and Click Next.

    Country Name (C): Use the two-letter code without punctuation for country, for example: US or CA.
    State or Province (S): Spell out the state completely; do not abbreviate the state or province name, for example: California 
    Locality or City (L): The Locality field is the city or town name, for example: Mountain View.
  11. Provide a file name and location to save your CSR.  You will need this CSR in order to enroll for your SSL certificate.  Click Next.

  12. Confirm the CSR Summary Information.  Click Next > Finish.

  13. A CSR file has been generated.  To copy and paste the information into the enrollment form,
    open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).

    NOTE: Upon completing the Certificate Wizard, it is important to leave the request pending for
    successful certificate installation. Choosing the option to delete the pending request from the
    Certificate Wizard will prevent installation of the certificate that is returned.
  14. Verify your CSR
  15. Proceed with the Enrolment. 
    NOTE: During the enrolment open the file you created from the above steps and copy the contents
    into the enrollment form when requested for the CSR.
Contact Information
          During the verification process, Symantec may need to contact your organization. Be sure to provide an email address, 
          phone number and fax number that will be checked and responded to quickly. These fields are not part of the certificate.
Once the certificate has been issued, follow the steps from this link to install the certificate on your server:  AR233
