One thing that I find myself doing alot is using Virtual PC or Virtual Server to create demos and test new applications. I’m using a syspreped .vhd file in order to get a clean server up and running in just a few minutes. One thing that have bugged me with my image is that even though I’m instructed to set the local admin password during the mini-setup it wold not change it.

So what’s causing this behaviour?

According to KB200607 the password on your master image, the one that you run sysprep on, must be _blank_, now how’s that for security?!?
