Global group

A group that can be used in its own domain and in trusting domains. However, it can contain user accounts and other global groups only from its own domain.

Globally unique identifier (GUID)

Part of the identifying mechanism generated by Active Directory for each object in the directory. If a user or computer object is renamed or moved to a different name, the security identifier (SID), relative distinguished name (RDN), and distinguished name (DN) will change, but the GUID will remain the same.

Group Policy

Setting of rules for computers and users. Group Policy stores policies for file deployment, application deployment, logon/logoff scripts, startup/shutdown scripts, domain security, Internet Protocol security (IPSec), and so on.

Group Policy Object (GPO)

A collection of policies stored in two locations: a Group Policy container (GPC) and a Group Policy template (GPT). The GPC is an Active Directory object that stores version information, status information, and other policy information (for example, application objects). The GPT is used for file-based data and stores software policy, script, and deployment information. The GPT is located in the system volume folder of the domain controller.
