Who is in a group?
NET GROUP "MYGROUP" /DOMAIN
dsget group "CN=GroupName,DC=domain,DC=name,DC=com" -members
dsget group "CN=GroupName,DC=domain,DC=name,DC=com" -members -expandÂ

From within SQL Server you can run...
xp_logininfo 'MYDOMAIN\MYGROUP', 'members'

Best Practices
Run on Windows Server Core
Do not run other software or services on a Domain Controller
Adjust the startup order and set a BIOS password
Standardize the configuration of all domain controllers
Always start with a single forest.
Avoid an empty forest root domain
If using two-way forests trusts, consolidate forests
