Updated Active Directory capacity planning guidance published
We recently published Capacity Planning for Active Directory Domain Services. This is a a detailed and comprehensive set of guidelines to help optimize computing resources for DCs, including considerations for virtual environments. It's by Ken Brumfield, a Senior field engineer here at Microsoft, based on his extensive experience and research. This has been a frequently requested document over the years and the Active Directory documentation is grateful to Ken for sharing his expertise and time to fill this need.
