What’s your biggest maintenance headache on the network – and how are you solving it?

As far as I’m concerned, one of the things that gives me the biggest headache when it comes to network maintenance, is probably everything related to patch management. Oh, we do have an awesome patch management solution where I work, but the whole thing is still driving me insane occasionally. Patches breaking operating systems, patches not deploying properly, and patches being just plain frustrating. But unfortunately, they’re a necessary evil, and can even be a blessing on occasions.

But what about you, dear IT geeks? What’s your biggest maintenance headache on YOUR network – and how are you solving it?
