How to publish the CRL on a web server (Manually and Automatically)
On the Publish CRL popup dialog box, ensure that New CRL is selected, and then click OK. If you do not see an error, check the folder on the Web server and confirm that it now contains one or more files with .crl extensions. If you do see an error, it is likely that there is a syntax error or permissions error that must be corrected before the CRL can be published to the separate Web server.
