Hi,

I"m a big believer of having a domain for businesses once they have 3 or more computers sharing files, and having employees with a medium or high turnover rate.  

I have a client with 8 workstations and while I have convinced them to purchase a Windows 2012 R2 Essentials server and add all their machines to a domain, they aren't convinced that the security was worth the expense (Server was under $2000), and all the workstations already had Pro OS's, so cost was not significant.  

Are there any good white papers on how a domain can help protect from various security standpoints?

Thanks!
