Windows DNS Queries Failing

I was putting together a PoC late last year and encountered an issue that I've not seen before that was caused by some functionality within Windows 2008 that I did not know existed at the time. In fact, no one who I've mentioned it to since knew about it either. It seemed sufficiently obscure that I thought I should write about it quickly. In the PoC, I had created a Windows domain based on Server 2008 R2. Setting that up was simple enough and I'd done it many times before. What I began to notice though was that DNS queries…

Adding disks to 2008 R2 Server Core VMs

In a lab environment, sometimes anything can go. Solutions aren’t always standards compliant or don’t always follow best / sensible practices. One that I can’t shake off though is using separate drives in my VMs for operating systems and data. It’s too ingrained. Given my new found penchant for using Windows 2008 R2 Server Core for VMs in my lab though I hit a little niggle that I thought I ought to note down for when I inevitably forget about it.

The install doesn’t autorun (Windows Explorer does this normally but Windows Explorer isn’t there). Even if you run setup64.exe manually it won’t help. If you run setup64.exe /? though you get a little…

Windows 2008 - Full Fat or Diet?

Out of curiosity (cats give it a bad name in my opinion) I recently chose to do a little experimentation. No bunsen burners and weird coloured liquids though, I wanted to do a light weight comparison of Windows Server 2008 R2 vs Windows Server Core 2008 R2 in my home lab. Let it never be said that I don’t know how to have fun! It was a rather simple comparison with a fairly simple aim: I wanted to know if there was a difference in how many resources were consumed on an ESXi host (specifically one of my low…

Windows Server Versions (Requirements)

I often forget half of this stuff so I thought it might be cunning to put some of it into a post. Sorry if it goes on a bit, some of the numbers change depending on your choice of Service Pack and it was easier to split that sort of thing into separate tables. Windows Server 2003 SP1 Requirements and Limits [TABLE=2] Windows Server 2003 SP2 / R2 Requirements and Limits [TABLE=3] Windows Server 2008 Requirements and Limits [TABLE=5] More information about Windows 2008 can be found here.…
