Disk performance information missing on Windows 2012 R2 – Blast from the past!

Posted by in Windows Server

Recently, I replaced a disk in my iScsi NAS. Since I wasn’t using any RAID on the disk I was replacing, I decided to copy data from old volume to new using robocopy. As my copy continued in the background, I curiously turned to the performance tab of task manager: As you may notice in the screenshot above, there was no disk information in the performance tab! I had a chuckle when I saw that. I remembered by Windows 2000 days and the trusty diskperf command. You can reference diskperf…read more

Posted by in Windows Server

In Part 1, I provided with walk through of how to install DHCP and configure scope on your newly installed DHCP server. In this post, we are going to setup failover between two servers.

Step-by-Step Configure DHCP Failover with 2012 R2 – Part 1

Posted by in Windows Server

Many times in my past years of IT, I wanted to have DHCP load balancing and high availability. It was possible by creating non-overlapping scopes etc. but that was all manual labor of making sure you don’t have overlap and all the headache that comes with careful planning and monitoring. the other option was to create clustered DHCP service. Well, that was convoluted too! Not sure why, but I always disliked the idea of having to maintain two machines with shared storage and other requirements. That’s why I liked how Exchange 2010…read more

Posted by in Hyper-V, Windows Server

In Part 1 of this article, we discussed how you can route between VMs on same host using networks connected to “Internal” virtual switch. Now let’s look at how to route between VMs when your lab consists of more than one hosts. Obviously, what I am going to cover isn’t the only way to do this but is one of many. I can certainly go on an on about all other options but I am trying to show the simplest possible one. Lab Setup For this lab, we are going…read more

Routing for Hyper-V Lab – Part 1

Posted by in Hyper-V, Windows Server

Most of us IT Pros usually have a lab of some kind. Mostly running some form of virtualization and if you are Microsoft savvy, chances are you are running Hyper-V either on Windows 7/8 pro edition so you can carry your lab around with you or have a Windows Server with Hyper-V. When we try to mimic real world complexities in these labs, routing becomes one essential component of these labs. Most of the times we are squeezed for resources and if you are like me, you would like to…read more

Installing WordPress on Windows Server 2012

Posted by in Windows Server

Note: Article updated to reflect changes as of February 2016 Installing WordPress on Windows Servers have been a challenge for me in the past. Mostly because of my ignorance to web development and the pre-requisites such as PHP and MySQL. Pre-requisites especially because I didn’t know where to get it, how to install it and ofcourse searching the web always gave me an answer, it was never simple or easy. Easy compared to what Microsoft Web Platform Installer has to offer. Web PI was an accidental discovery on my part…read more

Error: 0x800f0906 Adding GUI features on Windows Server 2012 Core

Posted by in PowerShell, Windows Server

I have always preferred to have least amount of overhead possible when running Server workloads. For the same reason my Hyper-V lab infrastructure is configured to run Windows Server 2012 Core. There are times however, when you may want to have GUI. So I set out to configure one of my servers from Core to minimal GUI. Knowing the cmdlets and options I assumed it would be as simple as running: Add-WindowsFeature Server-Gui-Mgmt-Infra –Restart Murphy never fails to surprise. I got this error instead: Add-WindowsFeature : The request to add…read more

Posted by in Firewall, PowerShell, Windows Server

If you are Microsoft’s volume license customer or an MSDN subscriber, the question of tracking usage of your volume license activation may have surfaced. You may already know what Volume Activation Management Tool (VAMT) is. If you aren’t, you can read more about it here.   Since I often build and rebuild my lab VMs, I keep track of my licenses using VAMT 3.0. Today, I built a new physical server that is going to be a Hyper-V host within my lab infrastructure. I chose to build it with minimal…read more

Enterprise Root CA Web Enrollment – RTFM, but what if I didn’t?

Posted by in Windows Server

I was building Enterprise Root CA in my lab and was in rush so ofcourse, I did not read the fabulous manual and went forward with installing the Enterprise Root CA without installing IIS. I did know IIS is needed for web enrollment but did not care to check if it was already installed. It sure wasn’t. So the Root CA was installed but I could not request certificates using web enrollment. I went ahead and installed IIS and enabled ASP after the fact but web enrollment still wasn’t going…read more

Exctrlst.exe – The case of missing Performance Coutners

Posted by in Windows Server

Recently I wrote about how to fix Corrupt of Missing Performance Coutners on a Windows Server. If you read the KB Article mentioned, it may sound complicated. One of the steps is to go through registry and find all services that have performance subkey. This could be very time consuming and tedious. Also, if you missed, the article does mention you have to make sure you rebuild counters from other programs such as Exchange Server and SQL server among others. It’s not part of rebuild process outlined in the KB….read more
