The following authentication error could occur while starting Author-it using the remote desktop (RDP) connection.
Your desktop connection failed because the remote computer cannot be authenticated. A revocation check could not be performed for the certificate.
When you connect via RDP to Author-it, this is what normally happens:
- Your browser connects to the RDP server.
- The RDP server sends your browser a public key and a certificate.
- Your browser tests the validity of the certificate by connecting via a normal website (HTTP) connection to a Certifying Authority, which compares the Author-it certificate to its Certificate Revocation List (CRL) and approves the certificate, allowing you to continue and make the connection.
However, if your organization has a Firewall that limits normal website (HTTP) connections (perhaps as a means of limiting Internet browsing), the Firewall can block the last step in the above process, and you will you see the warning screen with its message A revocation check could not be performed for the certificate.
So, the cause of this problem is that your workstation cannot make a normal Internet connection to the Certifying Authority used by Author-it, http://www.startssl.com. This could be a problem for all workstations in your organization, or just this one workstation, depending on your IT administration settings.
