We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
When it connects to your Internet Information Server (IIS) 4.0 server, a browser that needs to provide a client certificate may not show client certificates that originate from a certain Certification Authority. This may occur even after you have imported the Certification Authority root certificate into the IIS 4.0 server's Trusted Root Certification Authorities certificate store.



CAUSE
The IIS 4.0 server to which you are connecting does not have the Certificate Authority's root certificate installed correctly.



RESOLUTION
To resolve this problem, follow these steps to reinstall the Certificate Authority's root certificate on the IIS computer:  On the IIS server, start Microsoft Internet Explorer. On the Tools menu, click Internet Options. On the Content tab, click Certificates. Click the Trusted Root Certification Authorities tab, and remove any certificates that point to the Certificate Authority that issued the client certificates. To do this, select the certificate that you want to remove, click Remove, and then click Yes for each dialog box that you receive. Click Close, then click OK to clear any remaining dialog boxes. Obtain a copy of the Certificate Authority root certificate. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
