Managed PKI for SSL- Certificate Signing Request (CSR) Generation Instructions for Microsoft IIS 5.0


This document provides instructions for generating a Certificate Signing Request (CSR) for Microsoft IIS 5.0. If you are unable to use these instructions for your server, Symantec recommends that you contact Microsoft. 

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 or your password and generate a new one, your SSL Certificate will no longer match.
NOTE: If you are renewing a previous certificate with IIS that has a 1024 bit key length, refer to this link for steps on creating
a new CSR with a 2048 bit length without removing the previous certificate

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

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

  1. Click Start > All Programs > Administrative ToolsInternet Services Manager (IIS) Manager
  2. Double-click the Server Name > Web Sites folder
  3. Under Web Sites, right-click the corresponding Web site you wish to secure, and select Properties.

  4. Click Directory Security tab
  5. Under Secure communications, click Server Certificate

  6. Select Create a new certificate

  7. Select Prepare the request now, but send it later

  8. Enter a Name for the certificate. Please note that this is not the Common Name of the certificate request.  Select the bit length of 2048 for the certificate.

    NOTE: Do not check the box for Select cryptographic service provider (CSP) for this certificate
  9. 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, for example: XY & Z Corporation would be XYZ Corporation or XY and Z Corporation.
    Organizational Unit (OU): This field is the name of the department or organization unit making the request.
  10. Provide the Common Name and click Next.

    Common Name (CN): The Common Name is the Host + Domain Name. It looks like "" or "".
    NOTE: Symantec certificates can only be used on Web servers using the Common Name specified during enrollment.
    For example, a certificate for the domain "" will receive a warning if accessing a site named
    or "", because "" and "" are different from "".
  11. 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.
  12. 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.

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

  14. 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).

  15. Verify your CSR with the Symantec CryptoReport
  16. Proceed to Enrollment

    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.
