Microsoft Internet Security and Acceleration (ISA) Server 2006 Service Pack 1 introduces new features and functionality to ISA Server 2006 Standard and Enterprise Editions. The service pack includes configuration change tracking--registers all configuration changes applied to ISA Server to help you assess issues that may occur as a result of these changes, test button--tests the consistency of a Web publishing rule between the published server and ISA Server, traffic simulator, diagnostic Logging Viewer, support for integrated NLB mode in all three modes, including unicast, multicast, and multicast with Internet Group Management Protocol (IGMP). Previously, ISA Server integrated NLB-supported unicast mode only, support for use of server certificates containing multiple Subject Alternative Name (SAN) entries. Previously, ISA Server was able to use either only either the subject name (common name) of a server certificate, or the first entry in the SAN list, support for Kerberos Constrained Delegation (KCD) cross-domain authentication, and support for client certificate authentication in a workgroup deployment.
