Windows Server 2012 R2: Server Core Installation

Windows Server 2012 R2 Core Preview installs quite fast and we still have SCONFIG to help us setup:

Set Name

Set IP and DNS

Enable Remote Management

R2 Core SCONFIG

Then join the server to the domain:

R2 Core Domain join

If you haven’t changed the server name, then you have the change now. I already have the correct name for my server core, so I just hit “No” and then restart the server.

With that set, you are ready to administer the core server remote from Server Manager. In Server Manager go to “All Servers”, right click and choose “Add Servers”.

R2 Core Add Management 1

Search Active Directory for the name and select the server running Windows Server 2012 R2 Core.

R2 Core Add Management 2

The server is successfully added to Server Manager and is ready for Remote Management.

Migrating Network Policy Server (Radius) to Windows Server 2012 using PowerShell

21/06/2013 1 comment

 

As a consultant, I often help customers upgrading to the newest versions of Windows Server. Most of the projects I have been involved in, I start with the Domain Controllers. It is easy if you create a good plan and stick to it. Migrating Domain Controllers also means migrating Role Services. In the following, you will learn how to migrate Network Policy Server, NPS, Radius or what you call it 😉

The last project was an upgrade from Windows Server 2008 to Windows Server 2012.

Step-by-Step Guide

Starting at the Windows Server 2008 domain controller, we’ll have to use the netsh command to extract information about the NPS configuration to a XML file.

Here you see an overview of the NPS configuration that we want to migrate.

Login to the Windows Server 2008 server with an administrative account and start and elevated command prompt. Execute the following command to generate the XML file:

netsh nps export filename="c:\temp\DC2.xml" exportPSK=YES

“exportPSK” is required is you need to export the Shared Secrets for your RADIUS Clients.

Remember to store the file in a secure place, as it contain security information.

Move or copy the file to the target Windows Server 2012 server.

Start a PowerShell Prompt in elevated mode and run the following command:

Import-NpsConfiguration –Path c:\temp\dc2.xml

Running the command should only give you a new prompt and you are done!

Check out the Network Policy Server Admin user interface to secure that settings are migrated.

NOTE: That SQL Logging settings are NOT migrated, so please check under Accounting to see if the settings are in compliance with your policies.

If you are not switching IP on the target server, then you have to change all clients pointing at the NPS Server. In most migrations, I switch the IP of the Domain Controller/ NPS Server to match the old Domain Controller IP. Then I do not have to change DNS Server settings on a lot of servers and my NPS clients talk to the correct IP.
