Allow for client computers to access the CRLTo allow for client computers to access the CRL, follow these steps:
Allow for client computers to verify the certificate chainTo allow for client computers to verify the certificate chain, you must publish the root certificate in a location where client computers can access the certificate. Then, publish the distribution point through ISA Server that Microsoft Knowledge Base Article KB313072 describes. This distribution point is known as the authority information access (AIA) point.
The easiest way to allow for the client computer to verify the certificate chain is to publish the root certificates in the same location as the CRL. To do this, follow these steps.
Note If you have already issued a server certificate in which you need the client computers to be able to see both the CRL and the AIA, you must issue a new certificate.
