Installing VMWARE vCenter Server Appliance 6.0

Posted by in VMware

As I finally got around to installing first VMware 6.0 host in my lab environment, I decided to follow-up the installation of vCenter server appliance. This would allow me to manage the hosts I install later as well as the first host I installed moments ago. Not only that, I wanted to put in the infrastructure configuration in place before installing all the other hosts so I can achieve a level of consistency across the board. Installing vCenter server right after installing the first host would allow me to do…read more

Using 10Zig 5817q with Azure RemoteApp

Posted by in Azure

Recently, I had chance to test 10Zig 5817q thin client. While Azure RemoteApp isn’t listed on the product page as supported solution, that’s really what I needed to test as I didn’t have any on-premises deployment of Remote Desktop Services to test with. As a pre-requisite, I had already deployed my RemoteApp environment using Office 365 ProPlus template image from Azure. I published all applications such as Word, PowerPoint etc. I also configured a user to have access to published apps so I can test with it later. In this…read more

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

Free Load Balancer, wait what?

Posted by in KEMP, Load Balancing

Yes, you heard it right! KEMP Technologies provides a great load balancer for all workloads that can benefit from high availability. Today, it is making the Virtual LoadMaster (VLM) appliance available at no cost, even for production use! The free load balancer is a great offering for Development, Testing and Pre-Production environments. The free version is also supported for use in production! One of the use cases that strikes a chord with me is when I used to deliver trainings that needed use of load balancing. The training environment consists…read more

Reading email headers using apps for Outlook

Posted by in Exchange 2013, Exchange Server

Not too long ago, my fellow Exchange Server MVP Paul Cunningham recently published an article “Email Fundamentals: How to Read Email Message Headers” on his blog. Just like he mentioned, it’s pretty fundamental to emails but many struggle to read the headers and interpret it properly. I am all for making things easier. I will certainly not repeat what has already been said on his blog but wanted to complement his article with some more information. Exchange 2013 introduced integration with Apps for Office and Apps for Outlook. This opened…read more

SCVMM bare metal deployment failure with SuperMicro servers

Posted by in System Center VMM

I am not sure if laziness is side effect of automation or automation was born out of laziness, either way it has helped transform IT by increasing efficiency and reducing errors while performing repetitive tasks. It removes human element of error, it increases speed of deployments and it frees up valuable time of IT personnel which can be utilized for more important tasks that need more human brain cells. Ever since I came to know about SCVMM’s ability to deploy HyperV on bare metal hardware, I was eager to deploy…read more

Why is my HNV gateway not working?

Posted by in System Center VMM

I wrote an article on LinkedIn titled “Your gateway is responding! What is network virtualization doing to your network?”. This article is technical follow-up to the precursor. Not too long ago, I set out to create virtualized networks using Microsoft Hyper-V Network Virtualization (HNV) technology. I merrily went on with creation of required fabric and VM network components. I dedicated a host to HNV gateway function. I created Client VMs and a gateway VM. Here’s what the setup looks like: The setup is pretty simple. Two tenant VMs connected to…read more

Step-by-Step Configure DHCP Failover with 2012 R2 – Part 2

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. I am assuming that two DHCP servers are installed and a scope is configure already. So let’s go ahead and configure failover for given scope: In the resulting dialog, you can either select all scopes that exist or select scopes you want to provide failover for: On next page, you need to provide partner server. This…read more

Taking steps backwards – update BIOS on SuperMicro servers with DOS bootable

Posted by in Technology

Preface In todays’ age, you would think that when you have to update BIOS on your servers, you will be downloading an exe file and simply run it from your machine, ofcourse assuming you are running Windows on the machine. I was in for an unpleasant surprise of finding out that SuperMicro’s MicroCloud systems can only be updated using one of the two methods: Download BIOS zip file, which contains DOS executable and BIOS update bin file (which isn’t named .bin either!) Use IPMI and apply BIOS update OOB (out-of-band),…read more

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
