Error Code: 0x000000C4 when trying to install Windows 8 or 8.1 in Virtual Box

I tried installing Windows 8.1 Preview in Virtual Box and received the below error: (If memory serves me correctly this was the same for Windows 8)

Win 8.1 error

Run the following command and then try installing Windows 8.1 Preview again.

“c:Program FilesOracleVirtualBoxVBoxManage.exe” setextradata “VM Name” VBoxInternal/CPUM/CMPXCHG16B 1

This solved the issue for me. Found the information to the solution at this article here.

Meeting requests sent to a room mailbox, replaces the Subject, with the Senders name

We received a call today where a meeting request sent to a Room mailbox shows the meeting organiser’s name in the subject line.
This can be rectified by running the following:

Exchange 2010/2013:

Set-CalendarProcessing -identity “meeting room name” -DeleteComments $true -AddOrganizerToSubject $true -DeleteAttachments $true -DeleteSubject $true

Exchange 2007:

set-mailboxcalendarsettings -identity “meeting room name” -deletesubject $false -addorganizertosubject $false

Hope this makes your life a bit easier.

How to install the GUI for Ubuntu Server

I’m busy installing a server for my dad’s home and need a Graphical User Interface (GUI) for him to manage the server. I decided to install Kubuntu on my Ubuntu Server that I’m testing in virtual box. We are planning on getting him a Raspberry Pi running RaspBMC and the choices are OpenMediaVault or Ubuntu server to be the media server hosting his media to be streamed from.

Still deciding which way to go but here is a short tutorial on how to get the GUI installed on an Ubuntu Server after you have finished installing the Ubuntu Server Operating System.

1. After the server has booted you need to logon with the user name and password you set in the Ubuntu installation.
2. Now update Ubuntu by running: sudo apt-get update
3. After the update has downloaded the needed packages and finished the installation run: sudo apt-get install ubuntu-desktop (this will take some time to download the packages and install Kubuntu)
4. After the installation run: sudo reboot
5. Now you will load into the GUI and Windows users should be quite comfortable to use Ubuntu

Here’s a video of the test installation:
