In tip 3514, I described the subject problem and a workaround.
Microsoft Knowledge Base Article 293811 contains the following summary:
In March, 2001, VeriSign, Inc. announced that it had issued two digital certificates to an individual who fraudulently claimed to be a Microsoft employee. This issue is discussed at length in Microsoft Security Bulletin MS01-017
. VeriSign has revoked these certificates, and they are listed in the current VeriSign Certificate Revocation List (CRL)
. However, because the VeriSign code-signing certificates do not specify a CRL Distribution Point (CDP), it is not possible for any browser's CRL-checking mechanism to locate and use the VeriSign CRL
. Microsoft has developed an update that rectifies this problem
. The update package includes a CRL that contains the two certificates, and an installable revocation handler that consults the CRL on the local computer, rather than attempting to use the CDP mechanism.

Important Notes
| • | If you upgrade or reinstall any version of Internet Explorer or Windows, you must reinstall this update. You also must reinstall this update if you install any IEAK package, including a Single disk branding. NOTE :You do not need to reinstall this update if you upgrade to Windows XP, Windows 2000 SP2, or Internet Explorer 6. |
| • | If you choose to use a local copy of the VeriSign CRL manually rather than the CRL that is supplied with the update, be aware that the full VeriSign CRL is short-lived and must be refreshed weekly. |
| • | If you manually install the full VeriSign CRL before you install this update, you should install a new version of the CRL afterwards. |
