Hi, I have been reading "White Paper: Exchange 2007 Autodiscover Service" http://technet.microsoft.com/en-us/library/bb332063.aspx and "Publishing Exchange Server 2007 with ISA Server 2006" http://www.microsoft.com/technet/isa/2006/deployment/exchange.mspx I would like to know how to publish the redirecting Autodiscover web site when using "Scenario 4: Using the Autodiscover Service with Redirection" from the Autodiscover Service white paper. I think I should create an additional firewall rule for the Autodiscover web site, not using SSL, and using an additional IP address. Could anyone advice me on this please? Thank you very much
