9. Migrate Away From Internet Explorer
Last month's critical Internet Explorer security flaw, revealed in all versions of IE dating back to IE 5, should have been a wake-up call for anyone still using Microsoft's browser. Unfortunately, upgrading an entire office (and removing IE from those machines) takes time, so you're not out of line to be cautious in forcing users to upgrade. The good news: Unlike with most upgrades, users can easily adapt to Firefox, Opera, or Safari, so training needs will be minimal.
10. Clean Up the Mess in the Server Room
Cables sprawling everywhere (unlabeled, naturally). Dust accumulating in every crevice. Look under the pile of old CRTs, and you're likely to find a rat's nest--or worse. Most companies lock the janitorial staff out of the server room, but it's one of the places in the office that can benefit the most from old-fashioned cleanliness and organization. Take a slow day when most of the staff is out and spend a little time organizing and labeling spare parts, dusting out the servers, and otherwise tidying up. You'll be much happier once the clutter is cleared.
