I am installing Exchange 2010 SP1 in an existing Exchange 2007 environment. I have installed the CAS role on a server and am going through the list for cas configuration - cas array, dns entries, etc. At the current time users access OWA via the host name internally and an external_ip_address/owa externally. Existing certificate has the ip address as the name which generates an error internally. I want all users to use mail.domain.com for OWA internally or externally. I set a dns entry on my internal DNS server for mail.domain.com to point to the new Exchange server ip address and, on my ISP DNS server to an external but different IP address than OWA is currently using. I am running through the certificate wizard and figured I needed one certificate that includes mail.domain.com, autodiscover.domain.com, and hostname_of_the_new_server.domain.com but the wizard added hostname_of_the_old_server.domain.com to the list in the internal OWA section. Questions - (1) do I need to add CAS-Array.domain.com to the certificate and (2) why did the wizard add the old servers hostname to the list of OWA internal hostnames?
Thx
