This may be useful for granting users access to the internet by remotely updating their registry to know which DNS servers to use.
This topic provides background information about Active Directory Domain Services in Windows Server 2012 R2 and Windows Server 2012 and explains the process for upgrading domain controllers from Windows Server 2008 or Windows Server 2008 R2.
Beginning in Windows Server 2012, command-line installations are performed by using the ADDSDeployment Module in Windows Power Shell.
GUI-based promotions are performed in Server Manager using a completely new AD DS Configuration Wizard.
To help ensure consistent and predictable restart behavior for all devices and computers in your enterprise, including those that run Windows 8 and Windows Server 2012, you can configure the following Group Policy settings: Set machines to auto-install, prevent auto-reboot until desired time Policy: Configure Automatic Updates (Enabled)Configure automatic updating: 4 - Auto download and schedule the install Policy: No auto-restart with logged-on users (Disabled)WSUS deadlines: set to Fridays at 11PMPolicy: Configure Automatic Updates (Enabled)Configure automatic updating: 4 - Auto download and schedule the install Registry key: Enable the registry key discussed in Microsoft KB article 2835627Policy: Automatic Maintenance Random Delay (Enabled)Set Regular maintenance random delay to PT6H for 6-hour random delay to provide the following behavior:- Updates will install at the configured maintenance time plus a random delay- Restart for each machine will take place exactly 3 days later Alternatively, set a different maintenance time for each group of machines For more information about why the Windows engineering team implemented these changes, see Minimizing restarts after automatic updating in Windows Update.
Note it sets the value, it does not append so ensure you enter in the existing DNS servers as well as the new ones.
The recommended way to upgrade a domain is to promote domain controllers that run newer versions of Windows Server and demote older domain controllers as needed.
That method is preferable to upgrading the operating system of an existing domain controller.
This consolidation allows for all these components to use far less system resources, work consistently, respect the new Connected Standby state for new device types, and consume less battery on portable devices.
Because Windows Update is a part of Automatic Maintenance in Windows 8 and Windows Server 2012, its own internal schedule for setting a day and time to install updates is no longer effective.
