Hi guys 
I have installed SCCM 2012 R2 with 1511 upgrade in a home lab enviroment to learn this and to eventually become a pro with it.. lol 
  
I have completed installing everything and upgrading it to 1511 with MDT update 2 and Windows 10 ADK. 
Looking at some cbt nuggets videos after this,  I noticed I do not have an SMSadmin account at all in AD 
I am able to open the config manager console thought through a domain administrator account i created myself to use 
Added this account to be a member of domain admins, enterprise admins, schema admins, and local administrator groups 
  
Did I miss something? 
  
Remember this is a fresh install and all I have done is installed the pre-reqs and upgraded config manager to 1511 
  
This is what my logins look like in SQL Server Managment studio (attached), and the Pat\pat account is the domain admin account i mentioned above 
Should I just add the "pat" account to sysadmin?
