Leap Year bug plagues Exchange Server

In this post-Y2K era, it can be hard to believe that calendar-related bugs still are an issue. So you can imagine that IT admins the world over were surprised to discover that they were unable to install Microsoft Exchange 2007, set up new mailboxes or make various other configuration changes last Friday, all because of a Leap Year bug. The problems occurred if users started or restarted Microsoft's Exchange System Attendant service between 12 a.m. UTC on Feb. 29 and 12 a.m. UTC on March 1. Users could alleviate the problem by restarting their Exchange Server after those hours had passed--a fact that many discovered after wasting a full day trying to solve the problem. Here's hoping that Microsoft manages to sort this issue out before the next Leap Year.
