After a tremendous ordeal of trying to install OS X Lion on my January 2008 Mac Pro, I finally had a breakthrough. I discovered what appears to be a hardware incompatibility. To properly tell this story we’ll have to go back in time. In January of 2008 when this model of Mac Pro was available [...]

Description of Update Rollup 4 for Exchange Server 2007 Service Pack 3 It looks like Exchange 2007 SP3 RU4 has a lot of goodies in it. At least 5 of the items in this list are impacting the environment at my day job. While it’s good to see progress, I’m always wary of these updates [...]

I’m guessing from the amount of hits on the Drobo article from 2009 that people are still having problems with Drobos rebuilding the array in a decent amount of time. Ever since I got a DS4600 using standard RAID-5 I’ve been quite happy. Rebuild times on a 6TB volume are about 2.5 hours. Note: the [...]

For some bizarre reason, the thought at the top of my head last night at bedtime was… “I wonder if sometimes… open source developers deliberately code bugs or withhold fixes for financial gain?” If you don’t follow what I mean, here’s where I was: often times, large corporations or benefactors will offer a code fix [...]

This episode is very special to my heart because it’s the first show we did in our new studio (Whitey is still over Skype though). I think the [...]
Are you curious about the hard stats of messages running around your organization?

Last week I had to do some serious debugging on storage copy replication. We discovered that one of our SCC clusters had decided to quit replicating to the SCR node at the other site. We’re not sure why (we think it’s because the SCR node was rebooted and replication was not cleanly suspended), but the [...]

I’m all about negativity today. Sorry. Anyway, I’ve had something nagging at me for a while now and I think I’ve just figured it out. Powershell is Microsoft‘s answer to having a dumb command line through the Win95 – Win2003 years and it’s quite powerful, as the name implies. Microsoft likes it so much that [...]
One item you’ve probably learned by now if you’re an Exchange admin working on a 2007 deployment is that Microsoft has changed the behavior of the recipient update policy. Most of you won’t care about this and that’s just fine. You shouldn’t. I would dare say that if your Exchange environment is engineered well and [...]
