Renaming Windows domain w/exchange 2007 from mydomain.ads to mydomain.local

I ran into a problem this week on a domain at a client. They have five servers in one domain - mydomain.ads

The Godaddy (Standard Multiple Domain (UCC) SSL Up to 5 Domains) certificate expired. They cannot renew a certificate with ads extension so I need to rename the internal domain as .local but I'm not sure of the impact I will hit.  If you have run through this process, please provide details of what you encountered so I can be better prepared.

Website hosted by 3rd party is already named mydomain.com

All servers are physical - not virtual
Server 7 - 2008 r2, DC running Backup Exec 2014
Server 6 - 2008 r2, running RDP/Terminal services, User shares and App DB
Server 5 - 2008 r2 DC running Exchange 2007 (locally) email address already use the .com extension from the website
Server 4 - 2003 Std - Only a DC
Server 3 - 2003 Std DC used for user shres
Server 1 - 2003 Std user shares and App DB

nor can they use a domain .local in their certificates
 Better to run a split dns with webfacing items using one address and lan items using the existing domain.

You don't have to rename the domain at all.
Simple change Exchange to use the external name internally as well.

Furthermore, renaming a Windows domain with Exchange installed is not supported and usually breaks Exchange. However it is completely unnecessary.
