DOCUMENT:Q248058 03-JAN-2002 [iis] TITLE :Error Message: HTTP 403.13 Forbidden: Client Certificate Revoked PRODUCT :Internet Information Server PROD/VER::5.0 OPER/SYS: KEYWORDS:kbOSWin2000 kbiis500prod2web kbhttp40313 kbProd2Web ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Services version 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you attempt to access an Internet resource, one of the following error messages may be displayed in the Web browser: HTTP 403.13 Forbidden: Client certificate revoked The page requires a valid client certificate CAUSE ===== An HTTP 403.13 error message is returned when a resource that the user is attempting to access requires a valid client Secure Sockets Layer (SSL) certificate that the server recognizes. This client SSL certificate must be installed in the Web browser, because it is used for authenticating the user of that browser as a valid user of the resource. The error message can also occur if IIS is unable to contact the server that stores the Certificate Revocation List (CRL) when checking for revoked certificates. If a CRL server is unreachable, the certificates are presumed to be revoked. RESOLUTION ========== In the Web browser that is displaying the error, install a certificate from a recognized Certificate Authority (CA). If a certificate from a valid CA is installed, then contact that CA to verify the certificate has not been revoked, and that their CRL store is online. If the certificate was created with Microsoft's Certificate Server, you will want to verify that the IIS server is able to directly see the Certificate Server. You can verify the path under the CRL Distribution Points and verify that the path is accessible from the IIS server. To do this, follow these steps: 1. In the Certificates Snap-in, expand Certificates, and then expand Personal. 2. Under the Certificates folder, double-click the certificate you are verifying, and then click the Details tab. 3. Verify the paths under the CRL Distribution Points. 4. Check the paths by trying to access them through Windows Explorer, (from Start, click Run or Internet Explorer). 5. If the paths are not accessible from the IIS server, then it is necessary to rectify the connection to allow the IIS server to connect to the Certificate Server.
