Upgrading a DC to Windows Server 2012 R2 Preview

6:18 am in Domain Controller, Preview, Upgrade, Windows Server 2012 R2 by mikeresseler

As a true geek I have downloaded Windows Server 2012 R2 Preview the minute it was available. After installing a few virtual machines from scratch and playing with a few features it was time to see how an upgrade would perform.

The first server (in my demo environment of course) is a Domain Controller. But before I could actually do the upgrade, I needed to do some additional work.

First, I got into issues when I chose the upgrade path and the ability to go online to search for updates. I’ve got this error notification and I couldn’t find any logs or reports on what was wrong. As always, community to the rescue and I found a post written by WorkingHardInIT that described the problem and the workaround for it. You can find the blogpost here: http://workinghardinit.wordpress.com/2013/07/02/in-place-upgrade-to-windows-server-2012-r2-preview-fails-with-windows-installation-encountered-an-unkown-error-and-cannot-continue/

As it states in the post, the trick is to ignore the Go Online to install updates now (recommended) and to choose No Thanks.

After that, I have gotten my compatibility report.

So I went to the URL that is included in the message but that didn’t got me very far. This article is about preparing a Windows 2000 or Windows Server 2003 Forest Schema for a Domain Controller that runs Windows Server 2008 or Windows Server 2008 R2.

I tried searching on the web for a newer version of this article but couldn’t find the good one. So let’s do this one without any documentation. (I know… Stupid but hey… it is a test environment :-))

On the ISO Image that was mounted on my Virtual Domain Controller, I browsed to support/adprep and there I found the ADPrep executable.

Now it is time to perform this schema upgrade. I do this in PowerShell (as an administrator) but you can do this in command prompt also.

image

I run adprep.exe /forestprep

image

Now I hit “C” to continue

image

And everything is being upgraded. For those who want to know exactly what is being done. This command executes the following schema changes:

From sch57.ldf till sch69.ldf and finally PAS.ldf.

Without further thinking I started the upgrade process again. (Hey, it was Monday when I did this ;-)) and I got another issue

image

I had to do the domain prep also. (I should have known this but…)

The command do use is ADPREP.EXE /DOMAINPREP

image

And now you can start the upgrade of your domain controller, sit back, relax, wait a bit and get a nicely upgraded domain controller.

Cheers,

Summertime: Enter the IT Pro Summer Grand Prix

10:03 am in Uncategorized by mikeresseler

I’m back in Belgium and with a little bit of luck I’ll be staying in Belgium for the next couple of weeks. The nice thing is that I returned to some great weather and that I really have the summer feeling going on at this moment.

But besides the fun the summer period is also good for something else:

During summer period things tend to go a bit more slowly at work. Many people are on holiday, projects get delayed or placed on hold temporarily and I get some more free time on my hands. For years now I use this free time to get myself up-to-date with various IT subjects and technologies.

Enter the IT Pro Summer Grand Prix!

Microsoft Belux has created a summer campaign that helps us to find some more information on Windows Server 2012 R2 and System Center 2012 R2. Both tracks are open as of today.

You can find the information and the tracks here: http://aka.ms/summergp

In August two more tracks will be released about the Microsoft Virtual Academy (www.microsoftvirtualacademy.com) and Infrastructure as a Service. Certainly worth checking those out…

And now… let’s race :-)
