exchange 2010 ucc certificate - internal fqdn problem
Posted on 2011-03-10
I inherited an active directory running 2003 server/exchange.
The internal AD domain name is *not* unique on the internet. The name is registered to a company completely unrelated to our internal network. The network has a valid registered public domain name.
I am currently installing Server 2008 and Exchange 2010, and am going to have probalems requesting a UCC cert with SAN's including someone else's public domain name.
1. Do I need to have the Exchange 2010 internal server name as a SAN
2. If I do need the internal FQDN, can I put *just* the hostname with no suffix (e.g., "exch10" instead of "exch10.public.domain" - where "public.domain" is someone else's registered domain name)
3. Can I use split DNS and create an A record combining the internal hostname of the Exchange 2010 server with my public dns suffix (e.g., "exch10.mydomain.com").
