You cannot configure a different Secure Socket Layer (SSL) certificate for each enterprise array member server in a Microsoft Internet Security and Acceleration (ISA) Server 2004, Enterprise Edition-based array.
Consider the following scenario. You configure an ISA Server 2004, Enterprise Edition-based server that uses SSL to help protect HTTP connections. When you configure the Web listener to listen to an SSL connection, you must select a certificate that is installed and shared on all the array members.
Additionally, when you use an SSL hardware accelerator for each member server in the array, each accelerator will have a unique certificate.
However, ISA Server 2004, Enterprise Edition requires that you use the same certificate for all member servers in the array.
ISA Server 2004, Enterprise Edition does not support assignment of multiple Web listeners for Web publishing. You cannot configure multiple Web listeners that use a different certificate for each Web listener and then assign each Web listener to a Web publishing rule.
Service pack informationTo resolve this problem, obtain the latest service pack for Internet Security and Acceleration Server 2004. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
