When a non-Windows 2000 client (for example, all Windows 9x and Windows NT clients) tries to enroll over the Internet with an Enterprise certification authority (CA) server, the following error message may be displayed:

Access is Denied.


This behavior occurs because non-Windows 2000 clients (that is, Windows 95, Windows 98, and Windows NT 4.0) do not support the Kerberos 5 authentication protocol, so they cannot enroll with an Enterprise CA unless the CA and Web server are hosted on the same computer as the domain controller.


The Web server must be able to read the list of certificate templates stored in the Active Directory on behalf of the client, and doing so requires support for delegation, which is available only using the Kerbeors protocol.
