Over the years, we’ve had a lot of fun in the TechRepublic forums talking about the blunders and silly things that end users do and say. Now, we’re turning the tables a bit and asking IT pros to tell about the worst blunder they have ever made in their IT work. This can include everything from config errors that took down critical systems to purchasing the wrong stuff.

I’ll say this … almost all of the bad blunders that I’ve ever made have come when I’ve tried to attack a problem too quickly, rather than thinking through all of the steps and potential outcomes before embarking on any potential fix. This has resulted in BSODs on Windows boxes, stopping network daemons on UNIX servers in the middle of a business day, and crashing a critical Exchange mail server. Ahhhh the memories.

Join the discussion and tell us your worst blunder.
