Request a Certificate Using a PKCS #10 or PKCS #7 File

  • Article

Applies To: Windows Server 2008

It is not always possible to submit a certificate request online to a certification authority. In these instances, you might still be able to submit a certificate request in the form of a PKCS #7 or PKCS #10 file. In general, you use a PKCS #10 file to submit a request for a new certificate and a PKCS #7 file to submit a request to renew an existing certificate.

Users or local Administrators are the minimum group memberships required to complete this procedure. Review the details in "Additional considerations" in this topic.

Additional considerations

  • User certificates can be managed by the user or by an administrator. Certificates issued to a computer or service can only be managed by an administrator or user who has been given the appropriate permissions.

  • The component that enables Web enrollment in this version of Windows is different from the component that enables Web enrollment in Windows Server 2003 and Windows XP. Windows Server 2003 CA Web enrollment pages must be updated to support both this version of Windows and earlier clients. For more information, see the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=63591).

  • If this is the first time you are accessing the Web server for a CA, you must add the server to the list of Trusted sites in Internet Explorer. Trusted sites can be added by selecting Internet Options on the Tools menu, clicking the Security tab, selecting the Trusted sites zone, and clicking Sites. In addition, the Web server for the CA must be configured to use HTTPS authentication.

  • If you submit the request and immediately get a message asking you if you want to submit the request even though it does not contain a BEGIN or END tag, click OK.
