Virtualized Mac OS X Freezes

I am running a virtualized Mac OS X machine in my VMWare Workstation but I noticed that after a period of inactivity the virtual machine would sometimes freeze.

The case of the duplicate SID’s

I encountered another interesting error during Exchange 2010 installation today. During the Organization Preparation I got the following error: The setup.log doesn’t give us much more detailed info: Remko WeijnenWas once an enthusiastic PepperByte employee but is now working elsewhere.

Exchange 2010 well-known object entry install error

Today I was testing the installation of Exchange 2010 in a VMWare sandbox environment. We created the sandbox to test migration from a 2003 AD and Exchange environment to 2008 R2 with Exchange 2010. We used a P2V to get real copies of the Active Directory and the AD upgrade to 2008 R2 was already […]

Renaming and hiding object in PowerPoint

I was working on a PowerPoint presentation that included screenshots that were using the Appear animation. I use it to only show a particular screenshot when I am actually talking about it. However when editing the slide, the screenshots hide the slide text which makes it difficult to edit it. And in the Animation Pane […]
