Changing The Suffix on a local/public PDC

I have a client with a Windows Small Business Server 2011 running Exchange (publicly accessible).  It was originally setup with a mydomain.local domain suffix, and has functioned properly to this day.  After getting help with installing a SSL certificate for Exchange recently, the Tech Agent (from Godaddy.com) informed us that the .local suffix "isn't allowed anymore" and that the domain name should be changed with a .com suffix.  We do own the domain name it is suggested to be changed to.  Is this a straightforward reconfiguration?  Could anyone lead me to a tech bulletin that might outline the proper steps to do this without breaking our network functionality?

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hello,

I'm presuming that the certificate is for Exchange and Remote Web Access.

Details for requesting and installing an SSL Certificate in SBS 2011 can be located here:
https://technet.microsoft.com/en-us/library/cc546059.aspx

You're  Internet Address Management Wizard should have already been setup with your domain name so it should be something like:  remote.domainname.com or mail.domainname.com.

When requesting the new certificate this internet address is the only address you need to request.  You don't need to request a certificate for the local domain name.

Hope this make sense.

David: We already have the SSL cert installed and functioning properly.  As stated in the subject, I need direction for changing the domain name suffix on the PDC.
Toni: Does this wizard/tech document apply to a change in domain name on a PDC?
Toni UranjekConsultant/TrainerCommented:
Wizard will let you specify external domain and internal domain and set up DNS accordingly.

You can't change the domain name of the local network.  The only thing you can change is the Internet Address name which applies to Exchange and IIS.
