Re: In a similar vein
Back early on in the Windows XP to 7 migration we needed to test the automated deployment tool, so we could see how the SCCM would actually deploy the installer image.
So, a simple, near default, Windows 7 build with no software installed was created as a test by the project team to deploy to a couple of systems in a lab.
Unfortunately, it was deployed to the early adopter test group, where all the monthly desktop updates go to be tested before being pushed out organization wide. This is the majority of IT, including the helpdesk.
To get things moving along quickly, it was pushed out as mandatory, immediate and requiring a forced immediate installation including restart.
Thus, the entire helpdesk and most systems in IT were simultaneously trashed in the middle of the working day before someone managed to kill the deployment.
