Log on to a Windows Server 2008-based or Windows Server 2008 R2-based Domain Controller.When you’re running into problems and don’t mind the loosened security settings, you can always (temporarily) turn on the “Allow cryptographic algorithms compatible with Windows NT 4.0” setting on every Windows Server 2008 and Windows Server 2008 R2 you need it. Now, of course, not migrating to Windows Server 2008 (R2) is a bit excessive. For Windows XP and Windows Server 2003 an update is available to correct this problem. You never hope to encounter a Windows NT 4.0 environment in a merger, acquisition, or divestiture situation, but one can never be sure…Īlso, you may experience problems in environments merely containing Windows Server 2008 and Windows Server 2008 R2 Domain Controllers when you configure pre-Windows Vista SP1 clients to join the domain though Windows Deployment Services or the Microsoft Deployment Toolkit (MDT). Without the ability to build a trust between the source and target domain, one cannot migrate objects from a Windows NT4 domain. While this does not seem like a big deal, it might be in the light of the Active Directory Migration Tool (ADMT). This policy is configured to prevent Windows operating systems and third-party clients from using weak cryptography algorithms to establish NETLOGON security channels to Windows Server 2008-based domain controllers. When you promote a server to a Domain Controller, a screen containing this message is displayed, right after the Welcome screen: Windows Server 2008 and Windows Server 2008 R2 Domain Controllers have a new more secure default for the security settings named “Allow cryptographic algorithms compatible with Windows NT 4.0”.

While upgrading your Active Directory Domain Controllers, Domain Functional Level(s) and Forest Functional Level to Windows Server 2008 and Windows Server 2008 R2 offer additional functionality compared to previous versions, also a couple of caveats exist, that I think you should be aware of.
