Active Directory

Active Directory (AD) is a Windows-based directory service used by the entire Suffolk Community. The service holds user accounts, computer accounts and groups, and stores security information. It’s also used to centralize authentication and administration of Windows hosts. ITSIG provides and maintains a single domain AD forest ( for department use, including supporting services such as DNS, WINS, Kerberos, and Time Synchronization.

Active Directory Services

ITS Infrastructure Group maintains the forest root for the AD forest. In addition, the Infrastructure Group is responsible for the following:

  • Schema: The schema controls how objects are defined in AD. Occasionally, it is necessary to make additions to the schema. All such changes are handled by the Infrastructure Group. Schema changes will be thoroughly tested before being implemented.
  • DNS for AD: Infrastructure Group maintains AD service records in DNS for the forest.

To log in to Active Directory, you must know your user name, password and domain. This documentation has been written to reference the domain, or ADM for short.

Your user name is the first letter of your first name, then your full last name. For example: Name = Joe Smith; username = jsmith.

Changing Your Password

You are able to change your password at any time once you are logged into Active Directory (AD). There will be times when AD will force you to change your password. Usually, you will see a pop-up window informing you that "Your password will expire in [x] days. Do you want to change your password now? Yes / No?."
