What is Group Policy?
Group policies are computer and user configurations that can be enabled to secure server and host infrastructure.
There are two basic components of Group Policy, they can be divided into Group Objects and Group Policy Settings.
Group Policy objects -Part of Active directory that can be configured with various settings, they are either user or computer configuration setting and can be applied to users or computers, These objects are stored within GPO containers which are stored within the Active Directory Database, each of these objects have a unique Global identifier called a GUID.
Group Policy Settings -These are settings that apply to the policy, for example Enabled,Not configured, Disabled. They perform an action. They are stored within the Sysvol folder.
Group Policy can be linked to Local Policy, Sites, Domains,and Organisational units.
On a new install there are two default Policies that are applied:
Default Domain Policy(e.g Passwords, account lockout policies) Try not to touch this one two much as it’s not recommended.
Default Domain Controller Policy.
