Documentation and articles say when installing SQL Server (2012) you must use a service account when installing on an active directory domain controller (Windows Server 2008 R2 Standard). Says that Local System won't work. I've seen one domain controller server where all SQL services were set to Local System. So is this really true and forced by the SQL installer? There are tons of other services on a domain controller that run as Local System. Also noticed that the sql installer forces you to use Local System on the SQL Browser account, even on a domain controller. So is this just good advice to use a service account, or is it really a functionality problem?
This is in a small office 5 to 20 users situation.
