The top priority for every Windows administrator for the upcoming week should be testing Daylight Saving Time patches, says Dave Bermingham, director of product management, Windows Solutions Marketing, for SteelEye Technology Inc., a provider of data protection and applicaiton availability products for Windows and Linux.
"My advice is to any customer is to test," says Bermingham. "Gather all the advice you have, not only from Microsoft but from all your application vendors, and document it all."
Bermingham recommends that once customers have gathered all that information, they head into their labs and "roll the clock forward to the day before Daylight Saving Time." Then, he says, "Having applied the patches, go home, and come to work the next day and see how your lab survived the changeover."
According to Bermingham (who has a blog about DST 2007), Microsoft is doing a great job at keeping people informed, but, he says, "Microsoft is realizing that there are things that were not done right." Some patches out there are "breaking things," he says, noting that he's heard of environments where Exchange would not mount after an admin applied the DST patch.
