To generate a CSR for Microsoft IIS 7.0, perform the following steps:
1. Choose Start > Administrative Tools > Internet Information Services (IIS) Manager
2. In the IIS Manager, choose your server name
3. In the Features pane (the middle pane), double-click the Server Certificates option (Figure A) located under the Security heading.

4. You will notice two default certificates already installed on this server. To begin the process of requesting a new certificate, from the Actions pane, choose the Create Certificate Request option as shown below in Figure B.

5. The first screen of the wizard asks for details regarding the new site.  (Figure C).

All the fields need to be filled in. In order to fill in this form consider:

- 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: Berkeley.
- 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 Corportation or XY and Z Corportation.
- Organizational Unit (OU): This field is the name of the department or organization unit making the request.
- Common Name (CN): The Common Name is the Host + Domain Name. It looks like “www.company.com” or “company.com”.

Note: VeriSign 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”.

6. Click Next to continue.
7. The next screen of the wizard asks you to choose cryptography options. The default, Microsoft RSA SChannel Cryptography Provider is fine. A key length of 1024 or 2048 for EV certificates. (Figure D)

8. Click Next to continue.
9. Finally, provide a filename to which to save the certificate request. You will need the contents of this file in the next step, so make sure you know where to find it. (Figure E)

10. During certificate enrollment, you will be asked to submit the file. Open the file you created from the above steps and copy the contents. Then paste the contents into the window when requested in enrollment.
