While surfing the MS Office site, I noticed something at the top of the page... It read:

Speaking of Windows, I did a on-site support intervention, getting a laptop to join to a 2000 domain. It was rather poorly set-up and the event viewer of the DC was filled with errors from god-knows-what services. I started the wizard and had it running a few moments later. Can you say *KACHING* *KACHING*?
