Today’s enterprise infrastructure is dynamic, with new geographical locations and the networks associated with them being added or deleted on an ever-increasing basis. Microsoft represents network topology with directory objects called sites and subnets. The current state of the global network may not be reflected correctly within Microsoft Active Directory (AD). This causes an inefficient allocation of Windows services, or even outright outages of such basic services as user authentication and file availability. Microsoft does not offer tools to reveal and resolve such serious issues. Infoblox IP Address Management (IPAM) integration with Microsoft AD Sites and Services fills that gap.
