Exchange 2013 2007 CoExistence Frozen Transport Queues

We’re in the middle of an Exchange 2007 to 2013 On Premise migration, and we haven’t been having the best time. After a major mail crash in 2011, every time we’ve attempted to move off the recovered server, either to Exchange 2010 or to a freshly built Exchange 2007 setup, we’ve encountered major, migration stopping issues.

My worst night.

The title is melodramatic, I realize this, but it’s true. I’ve done bad things, had worse things done to me, and had nights that were a lot harder to deal with at the time, but this is the night I always come back to. It’s the night that I feel worst about, and the night I regard as my biggest failure. I had the chance to prevent the world from getting a bit worse, but instead I did nothing.

Full home audio without iTunes

I want to have speakers in every room of my house, and I want them to be able to play the same stations, or different ones. Basically I want to have digital FM radio across the whole house, so that as I walk from the living room, to the back yard the music doesn’t skip a beat. This is currently offered by Sonos at a ridiculous price, and was offered until 2012 by Logitech, with Squeezebox at a less ridiculous price. Squeezebox being discontinued, I’m not willing to sink my money or time into that, and Sonos is too expensive.

dcpromo fails with An error with no description has occurred on Server 2008R2

While working to get rid of all our 2003/2008 DCs to get our AD to a 2012 Native level I came across one 2008 DC that was extremely difficult to rid ourselves of. It was created about a year ago to replace our 2003 FSMO master, and had been running without major issue since then. After building a new 2012 VM, and DCPromo’ing it, I transfered the FSMO roles to a stable server and set out to demote and decommission the 2008 machine. Upon running dcpromo from an admin shell, the system began to detect the ADDS binaries, and failed. The message it failed with was an extremely helpful “Failed to detect if Active Directory Domain Services binaries were installed. The error was: An error with no description has occurred.” Lovely.

Bash script to automatically restart MySQL when website database connection is down

I’ve been noticing that periodically my MySQL service will hang and require a restart. It’s easy enough to SSH in and restart it, but I only catch it after the fact. So I wrote this little script which curls my website, sees that it’s down and restarts MySQL and shoots me an email with sSMTP. This only checks for the MySQL service not accepting connections from Apache. If there’s an error with Apache, or it’s not running this won’t do anything.
