There are two portions of every GPO. The Group Policy Template (GPT) is stored in the SYSVOL of each domain controller and the Group Policy Container (GPC) is stored in the Active Directory database. Each of these GPO portions has an associated version number that keeps track of how many changes have occurred to the computer and user portions within the GPO.

active directory windows group policyIn an on-premises AD environment, you would update the schema by running the Update-AdmPwdADSchema Windows PowerShell cmdlet with schema administrator credentials. Because AWS Microsoft AD is a managed service, I do not have permissions to update the schema directly. Instead, I will update the AD schema from the Directory Service console by importing an LDIF file.

microsoft security active directoryBecause Active Directory is a multi-master database, changes can be processed at any given domain controller (DC) in the enterprise regardless of whether the DC is connected or disconnected from the network.
For certain types of changes, Windows incorporates methods to prevent conflicting updates by extending the single-master model found in earlier versions of Windows to include multiple roles. Because an Active Directory role is not bound to a single DC, it is referred to as a Flexible Single Master Operation (FSMO) role. Currently in Windows there are five FSMO roles:
The solution should retrieve not only direct group membership, but indirect (through group nesting) too. Although the question is plain and simple, the solution is very interesting from various perspectives.

active directory windows dnsPermissions in Active Directory are defined by so-called security descriptors, which are stored as properties directly in the AD objects.
active directory sysadminFrom time to time you may want to delegate control of an AD security group to an unprivileged user. The group manager property is an LDAP property on the group object that contains the Distinguished Name of a given user account. The checkbox that allows the group manager to modify who is a member of this group is not an LDAP property with a boolean type, that would be too simple and not line up with the Microsoft security management methodology. It's implemented as an Access Control Entry (ACE) in the objects Discretionary Access Control Li (DACL). Think of it like the permissions when looking at the Security tab for a file. These can be manipulated programatically.
active directory windows sysadminDNSLint is a Microsoft Windows utility that can help you determine whether all DNS servers that are supposed to be authoritative for the root of an Active Directory forest actually have the necessary DNS records, and can resolve all of the necessary DNS records to successfully synchronise partition replicas among domain controllers in an Active Directory forest.
active directory windows sysadmin dnsThe local Group Policy object is always processed, followed by GPO. Site first, domain next, and OU last, including any nested OUs, from parent to child. The Block policy inheritance or No Override options can affect the presence or absence of Group Policy objects in the list of Group Policy objects to be processed, but cannot change their order. Computer policy is processed at startup and then user policy is processed when the user logs on. If user and computer policy settings specify different behavior, the computer policy will generally prevail.

These definitions were found to be most effective from both a best practice and compliance standpoint and are based on customer experience and recommendations from Microsoft.

active directory windows sysadmin best practiceThe domain controllers will wait up to 10 hours from time of creation to allow all domain controllers to converge their AD replication before allowing the creation of a Group Managed Service Account (gMSA). Workaround with Add-KdsRootKey –EffectiveTime ((get-date).addhours(-10)).
active directory windowsThink of a domain as a big data partition, which is also referred to as a naming context. Only domain controllers that are authoritative for a domain need to replicate all of the information within that domain. Information about other domains is not needed on those domain controllers. On the other hand, there is some Active Directory data that must be replicated to all domain controllers within a forest.
