2 TB: Using GUID File Allocation Tables (GPT GUID Partition Table)

2 TB Drives have been around a while and certainly building raid arrays over 2 TB has been possible for quite some time. If you haven’t stumbled across this read on. Why GPT? GUID Partition Table disks can grow to a very large size. As of July 2001, the Microsoft implementation supports a hard disk of up to 18 EB (Exabyte equal 1000 Terabytes). It is not that I am predicting Exabyte drives soon but more that Master Boot Record tops out at 2 TB. GPT is the partition table to use if you plan on exceeding 2 TB. How … Continue reading 2 TB: Using GUID File Allocation Tables (GPT GUID Partition Table)

Outlook 2010: How to change your default Contacts Address Book

Have you ever wondered how to change the default address book in Outlook when you are using Exchange. If you have ever sent an email and tried to find your contacts using the To: button you know that by default the Exchange Global Address Book is the first source of contacts. What a pain. I always find it difficult to locate where to change the default so I thought I would post it in case you are looking.

Small Server Room Design: Cooling for Seasonal and Sub-Zero Climates

A client of ours is currently going through not only an unseasonably cold snap but some of the coldest weather in the history of the North West, USA. His server room is well designed with cooling for the summer but who would have thought that cooling would fail in the fall and winter months. Yet it is, and with AC down his server room only takes 15 minutes to rise in to the 90s F. So he is left with the choice of securing his server room or cooling his server room by opening the door. It is a no … Continue reading Small Server Room Design: Cooling for Seasonal and Sub-Zero Climates

Branch Office: Removing an RODC from AD

Well eventually you are going to remove an RODC and if you are running in a test lab sooner rather than later. Microsoft has a TechNet Article which covers removing the RODC with the claim that AD metadata is removed. I have not found that to be entirely accurate. This post reflects my experience and the additional items which needed to be removed. This post reflects how to remove the RODC when the server has been lost or stolen, or in my case restored to an earlier backup. Note: If the RODC is still connected to the domain follow the … Continue reading Branch Office: Removing an RODC from AD

Scripting NTDSUTIL

NTDSUtil.exe is an Active Directory Utility which is used for a number of administrative tasks. In my blog I have talked about a number of administrative tasks such as defraging AD, removing AD objects and so on. Using scripts is some times easier and for that I have included a reference to a TechNet article which although short shows how easy scripting for this tool is if you know the commands you want to run. How to automate Ntdsutil.exe using a script http://support.microsoft.com/kb/243267 Here are some examples from the article: In the long form the following script returns a list … Continue reading Scripting NTDSUTIL

Windows 7: What to do if you can’t find a driver

I am not one to plug companies I wouldn’t use. So know this first, I have used Driver Detective. Some people out there will be upgrading to Windows 7 and will run into problems finding a driver. Now when I ran into the this problem in the early betas of Windows 7 I spent time looking for drivers online. I used some pretty specific techniques that everyday users would find impressive but I say are just plain time consuming. And I don’t have time for it. So for that reason I would like to introduce you to one of the greatest … Continue reading Windows 7: What to do if you can’t find a driver

48-Core Intel Processor – Leveraged by Barrelfish

Intel has released a research chip with 48 cores. Called a single-chip data center, its core selling point is that it uses dramatically less energy. What I noticed is that its new architecture leverages software memory control and messaging. As you will remember from my previous post on Barrelfish and next generation Windows, this architecture is designed without hardware level memory control allowing the operating system to control the use of cores and memory alleviating the current bottlenecks on performance. Those folks in the barrelfish project are slapping their lederhosen and clearing their throats with Ricola about this technology. “We’re very excited about … Continue reading 48-Core Intel Processor – Leveraged by Barrelfish
