File server permissions change auditing.

We’ve had some issues with admins improperly applying permissions in the past, and in recent times as well. Because of this, we’ve decided that maintaining permissions change logging to determine who it is that’s having issues learning how to apply permissions can get some extra training on how to appropriately set file ACEs. The issue with doing this is that it generates ~40GB of compressed Windows logs daily, or closer to 100GB uncompressed.  So, how can we use PowerShell to parse through the binary logs, store the info we need, and then get rid of the relatively gigantic evtx files?

ZFS on Linux NFS shares lost at reboot

On several occasions NFS has inexplicably stopped working with my ZFS shares under ZFS on Linux on Ubuntu Server 14.04×64. It seemed to happen every reboot, after checking the sharenfs property on each of the ZFS FS’ I found they were set properly, but still clients were getting access denied when trying to mount the share. Other times, even when they were able to re-mount the share they wouldn’t do so unless I manually triggered it.

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.
