Hi Greg, As promised: Publishing OWA Web Sites with ISA 2004 Firewalls: http://www.msfirewall.org/isa2004/2004owapub/2004owapub.htm Note that you'll have to wait for the ISA 2004/Exchange Server deployment kit for details on certificate deployment, or you can use the info in the ISA 2000/Exchange 2000/2003 deployment kit, since the certificate deployment issues are the same.
