How to solve a technical problem:

Kill some Zombies!

Client emails us in a panic because his email server for their sub-company is down. He has no idea why, it was working fine the day before and he hasn’t been messing with it. I spend most of the day bashing away at it, can’t find the cause.

Serendipitously, Comcast finally comes through with the second feed and new IP address so we can move this project out from under the main business and onto a separate firewall. Mail is already dead, the users won’t know if we move stuff around so we go with it. I re-write all of the firewall rules in record time, (That CSSA course paid off!) and disable all the rules for this project in the main firewall. At the time, I notice something I think is a little odd, but move on. I make the changes to DNS at a quarter to five. Nothing to do now but wait and see.

Go home, scrounge some dinner, zone on some tv, splatter about 500 zombies and generally turn off. My subconscious percolates.

Just a few minutes ago, Bam! that oddness in the firewall comes back into focus and I realize one of the rules I had disabled in the main firewall was the killer. Check the mail server, and thar she blows! Email for all!

The question now is, was one of our guys mucking around in there, or was this a 1st Rule violation?

My money is on the fish.
