Maybe I should answer this with a story. My first client was a highly respected professor. He bought a new Lexis and drove it 10,000 miles. One day, it wouldn’t start. He had it towed to the dealer. A serviceman called him a few hours later and asked “Sir, when was the last time you changed the oil”? He replied “WHAT”?
Yes, you guessed it. The professor neglected this simple maintenance task. He could have contracted out this task to a local shop that changes car oil. He didn’t and suffered the consequences. I see the same thing happen with computers and networks. Business owners neglect updates and don’t read logs. When some catastrophe happens, they ask “how could this have been avoided”? They could have checked logs and probably found errors 2-3 weeks before the catastrophe struck.
I have some good news. You can contract out this task to your network manager. He knows where to look for errors and any brewing problems. He can usually find and fix them before they create a computer or network outage. He will also follow a checklist that helps set high standards and consistent implementation. Yes, you will have to pay for this, but the costs of preventative maintenance are far lower than what you would incur if you suffer a computer or network outage.
