I am wondering if it is possible to change the Internet Domain Name on an SBS 2011 domain controller. For example, if you currently have 'office.contoso.com' as the Internet Domain Name, can the domain 'contoso' be changed to something different, like 'office.business.com'? I don't believe on SBS this can be done without serious repercussions, and even this Microsoft article seems to mention the same thing:
But I'm curious if this applies to all versions of SBS, or only older ones before 2011. Any ideas?
