Now when we've discussed the main functional level let's discuss 80 days forest confronts functional
levels as you know and 80 days forest can run a different functional levels and sometimes brazenly aided
as forest functional level makes additional features a way lable.
The most noticeable additional feature is Congress upgrade internal use Windows Server forest functional
levels.
When you raise the function therefore as functional level adding new domains is limited by the forest
functional level domain controllers must to use domain functional levels that are the same as a forest
functional level.
For example if the forest functional level is Windows Server 2012 our two you can not add a new domain
based on Windows server or two thousand eight are two domain controllers.
Additional features that are available with versions of Windows Server starting with Windows Server
2003 include trusts the basic feature of forests that all domain trusts are transitive trusts so that
with permission and a user in any domain in the forest can access any resource in the forest.
Then there's the next feature is forest trusts.
It's possible to set up trusts between 80 days forests to enable resource sharing forest trusts can
be fooled trusts or selective trusts.
The next feature implemented after Windows Server 2003 is linked while your application.
This feature improved Windows 2000 Server application and then managed of for group membership in previous
versions of Active Directory the membership attribute of a group replicated to a single value.
This meant that if two administrators changed the membership of the same group in two different instances
of 80 deaths during the same replication period the last right one the first changes made would be lost
because the new version of the group membership attribute replaced the previous one entirely with linked
while your application group membership is treated at the well your level.
Therefore all updated merged together.
This also greatly reduces replication traffic and additional benefit from the feature is the removal
of the previous group membership restriction that limited the maximum number of members to 5000.
The next feature is improved aided replication calculation algorithms the knowledge consistency check
around interest site topology generator use improved algorithms to speed up the calculation of the 80
days replication infrastructure and to provide much faster site link calculations and other features
support of raw DC.
As you might remember Roy disease are supported the Windows Server 2003 for us.
Functional level is C must be run in Windows Server 2000 8 or newer and it requires at least 1 Windows
Server 2000 8 or newer full domain controller as a replication partner.
Next up conversion of iron ID or a rigid person objects to user object with the help of this feature
you can convert an instance of an iron it or a rigid person object used for compatibility with certain
non Microsoft directory services and you can can convert it into an instance of a class User object.
You can also convert a user object to him iron it or a G Person object.
And the last but not least the activation and redefinition of attributes and object classes although
you cannot delete an attribute or object class in the schema.
The Windows Server 2003 functional level you can deactivate or redefine attributes or object classes.
All these features are introduced with Windows Server 2003 forest functional level the Windows Server
2008 for us.
Functional level does not add new forest wide features.
The Windows Server 2008 are two for us functional level at the ability to activate Active Directory
features such as Active Directory recycle bin.
This feature allows the ability to restore deleted Active Directory objects.
You can not roll back the forest functional level it features that require a certain forest level such
as Active Directory a recycle bin feature have been enabled although the Windows Server 2008 are to
Active Directory forest functional level introduced Active Directory.
Recycle Bin.
This feature had to be managed with Windows power shell.
However the version of remote server administration tools that comes with Windows Server 2012 and later
has the ability to manage the Active Directory recycle bin by using Google tools.
As for their Windows Server 2012 2012 our 2 and 2016 for us functional levels they do not provide any
new forest wide features.
However if you raise the forest functional level to one of these versions you can not add a new domain
run at an earlier domain functional level.
