Notes

  • To open Active Directory Users and Computers, click Start, click Control Panel, double-click Administrative Tools, and then double-click Active Directory Users and Computers.

  • Unless users refresh their security policy using the GPUpdate command, it will take a number of hours for the autoenrollment policy to take effect.

  • When autoenrollment retrieves a certificate that is configured to be stored on a smart card, you will receive a message when the certificate is ready to be stored on the smart card. If the message refers to a type of smart card that you do not have, click Cancel until the correct smart card type appears. You then provide the smart card PIN and the certificate will be stored on the smart card.

  • When autoenrollment enrolls for a certificate that requires user interaction for the enrollment process, you will receive a Certificate Enrollment message and an icon appears on your taskbar. Clicking that icon or message begins the certificate autoenrollment process.
