Preinstalled Trusted Root Certificates

The root CA certificates that are contained in the Trusted Root Certification Authorities store are trusted for all Windows applications that use public key certificates for security functions. Windows 2000–based computers include many preinstalled certificates in the Trusted Root Certification Authorities stores. The preinstalled trusted root certificates include root certificates from a variety of commercial CAs and Microsoft. Certificates that are issued by these trusted CAs are trusted on local computers for valid purposes. However, you might not want to trust the preinstalled root certificates, or you might want to add other certificates as trusted root certificates.

You can use the Certificates console to delete or add certificates manually for Trusted Root Certification Authorities stores on each local computer. You also can add trusted root certificates for groups of computers by using Public Key Group Policy.

In addition, you can use the Internet Explorer Administration Kit (IEAK) to create and deploy custom builds of Internet Explorer that have only the root certificates that you want for your enterprise. For example, you can create custom builds that include only a few trusted root certificates and then deploy those custom builds to groups of computers. The computers where the custom builds of Internet Explorer are installed have only the trusted root certificates that you specified. You can create different custom builds to meet the requirements of different groups in your organizations. For more information about using the IEAK, see the Microsoft ® Windows ®  2000 Server Resource Kit Internet Explorer Resource Guide .
