Exchange 2010 certificate confusion:  what names do I need?

reuniontitle asked
Last Modified: 2013-11-05
Ok, I'm working on my migration to Exchange 2010.  I'm about to get started, but I am totally confused about certificates.  I'm pretty sure from my research that I need a SAN certificate, but I'm clueless as to what names to put on it.  Here's my setup:

external mail domain:  abc.com

two sites with a cas array in each one.

site a:

casarray:  moarray.abc.com

server1 netbios name:  momx01

server1 fqdn: momx01.abc.local

server2 netbios name:  momx02

server2 fqdn:  momx02.abc.local


site b:

casarray:  utarray.abc.com

server1 netbios name:  utmx01

server1 fqdn:  utmx01.abc.local

server2 netbios name:  utmx02

server2 fqdn: utmx02.abc.local


I want all external users to connect to the casarray at site a (will nat through firewall) for mail.abc.com, autodiscover.abc.com, legacy.abc.com.  I want all internal users at site a to connect to moarray.abc.com for all resources.  I want all internal users at site b to connect to utarray.abc.com for all resources.

Can this be accomplished?  If so, how many certificates to I need?  Do I need one per server? Do I need one per array?  What names should be included on the certificate?


Thanks in advance for your help!
