1 00:00:06,400 --> 00:00:12,780 Now when we've discussed the main functional level let's discuss 80 days forest confronts functional 2 00:00:12,790 --> 00:00:20,390 levels as you know and 80 days forest can run a different functional levels and sometimes brazenly aided 3 00:00:20,470 --> 00:00:25,250 as forest functional level makes additional features a way lable. 4 00:00:25,270 --> 00:00:32,290 The most noticeable additional feature is Congress upgrade internal use Windows Server forest functional 5 00:00:32,290 --> 00:00:33,080 levels. 6 00:00:33,130 --> 00:00:40,270 When you raise the function therefore as functional level adding new domains is limited by the forest 7 00:00:40,300 --> 00:00:49,210 functional level domain controllers must to use domain functional levels that are the same as a forest 8 00:00:49,210 --> 00:00:50,670 functional level. 9 00:00:50,710 --> 00:01:00,250 For example if the forest functional level is Windows Server 2012 our two you can not add a new domain 10 00:01:00,250 --> 00:01:06,170 based on Windows server or two thousand eight are two domain controllers. 11 00:01:06,190 --> 00:01:14,350 Additional features that are available with versions of Windows Server starting with Windows Server 12 00:01:14,350 --> 00:01:25,120 2003 include trusts the basic feature of forests that all domain trusts are transitive trusts so that 13 00:01:25,120 --> 00:01:33,260 with permission and a user in any domain in the forest can access any resource in the forest. 14 00:01:33,530 --> 00:01:36,910 Then there's the next feature is forest trusts. 15 00:01:36,910 --> 00:01:45,460 It's possible to set up trusts between 80 days forests to enable resource sharing forest trusts can 16 00:01:45,460 --> 00:01:49,250 be fooled trusts or selective trusts. 17 00:01:49,270 --> 00:01:57,480 The next feature implemented after Windows Server 2003 is linked while your application. 18 00:01:57,520 --> 00:02:07,240 This feature improved Windows 2000 Server application and then managed of for group membership in previous 19 00:02:07,240 --> 00:02:14,410 versions of Active Directory the membership attribute of a group replicated to a single value. 20 00:02:14,410 --> 00:02:22,720 This meant that if two administrators changed the membership of the same group in two different instances 21 00:02:22,720 --> 00:02:32,230 of 80 deaths during the same replication period the last right one the first changes made would be lost 22 00:02:32,560 --> 00:02:40,420 because the new version of the group membership attribute replaced the previous one entirely with linked 23 00:02:40,440 --> 00:02:45,610 while your application group membership is treated at the well your level. 24 00:02:45,910 --> 00:02:49,330 Therefore all updated merged together. 25 00:02:49,330 --> 00:02:58,210 This also greatly reduces replication traffic and additional benefit from the feature is the removal 26 00:02:58,210 --> 00:03:06,990 of the previous group membership restriction that limited the maximum number of members to 5000. 27 00:03:07,000 --> 00:03:14,830 The next feature is improved aided replication calculation algorithms the knowledge consistency check 28 00:03:14,830 --> 00:03:23,540 around interest site topology generator use improved algorithms to speed up the calculation of the 80 29 00:03:23,540 --> 00:03:32,090 days replication infrastructure and to provide much faster site link calculations and other features 30 00:03:32,290 --> 00:03:34,290 support of raw DC. 31 00:03:34,510 --> 00:03:41,230 As you might remember Roy disease are supported the Windows Server 2003 for us. 32 00:03:41,230 --> 00:03:52,240 Functional level is C must be run in Windows Server 2000 8 or newer and it requires at least 1 Windows 33 00:03:52,240 --> 00:03:59,920 Server 2000 8 or newer full domain controller as a replication partner. 34 00:03:59,920 --> 00:04:07,580 Next up conversion of iron ID or a rigid person objects to user object with the help of this feature 35 00:04:07,600 --> 00:04:16,120 you can convert an instance of an iron it or a rigid person object used for compatibility with certain 36 00:04:16,450 --> 00:04:25,560 non Microsoft directory services and you can can convert it into an instance of a class User object. 37 00:04:25,600 --> 00:04:30,930 You can also convert a user object to him iron it or a G Person object. 38 00:04:31,090 --> 00:04:39,520 And the last but not least the activation and redefinition of attributes and object classes although 39 00:04:39,520 --> 00:04:45,580 you cannot delete an attribute or object class in the schema. 40 00:04:45,640 --> 00:04:54,770 The Windows Server 2003 functional level you can deactivate or redefine attributes or object classes. 41 00:04:54,790 --> 00:05:02,500 All these features are introduced with Windows Server 2003 forest functional level the Windows Server 42 00:05:02,500 --> 00:05:04,210 2008 for us. 43 00:05:04,210 --> 00:05:09,520 Functional level does not add new forest wide features. 44 00:05:09,620 --> 00:05:19,030 The Windows Server 2008 are two for us functional level at the ability to activate Active Directory 45 00:05:19,040 --> 00:05:23,260 features such as Active Directory recycle bin. 46 00:05:23,270 --> 00:05:29,450 This feature allows the ability to restore deleted Active Directory objects. 47 00:05:29,450 --> 00:05:37,280 You can not roll back the forest functional level it features that require a certain forest level such 48 00:05:37,280 --> 00:05:46,790 as Active Directory a recycle bin feature have been enabled although the Windows Server 2008 are to 49 00:05:47,000 --> 00:05:52,550 Active Directory forest functional level introduced Active Directory. 50 00:05:52,550 --> 00:05:54,170 Recycle Bin. 51 00:05:54,260 --> 00:05:57,980 This feature had to be managed with Windows power shell. 52 00:05:58,220 --> 00:06:07,340 However the version of remote server administration tools that comes with Windows Server 2012 and later 53 00:06:07,610 --> 00:06:14,320 has the ability to manage the Active Directory recycle bin by using Google tools. 54 00:06:14,330 --> 00:06:25,070 As for their Windows Server 2012 2012 our 2 and 2016 for us functional levels they do not provide any 55 00:06:25,070 --> 00:06:27,050 new forest wide features. 56 00:06:27,230 --> 00:06:35,540 However if you raise the forest functional level to one of these versions you can not add a new domain 57 00:06:35,810 --> 00:06:39,500 run at an earlier domain functional level.
