Publish VMware vSphere client with TMG 2010
0There are situations in small environments when you need to access your ESX/ESXi server from the internet, for troubleshooting or just to create or restart a virtual machine. I bet that’s a piece of cake for some of you, but what if you have a TMG server as a firewall. Well…things are not so easy any more, but they are not complicated either. If you have a situation like this, where a TMG 2010 server acts as a firewall for you or for some of your clients, and want to access an ESX/ESXi server from the internet, then you came to the right place.

Transitioning from 2003 Active Directory to 2008 R2
0Finally, you got the green light for upgrading your Active Directory environment from 2003 to 2008 R2. As you might know the upgrade process is simple, if those domain controllers are 64 bit, because you can do an in-place upgrade. I talked about in-place upgrade of a domain controller here. Unfortunately the process is very different if your domain controllers are 32 bit. First because you need extra hardware; second, that hardware needs to support Windows 2008 R2; and third, you need play with some Active Directory advanced settings. (more…)
Installing Remote Desktop Services in Windows 2008 R2
0I’ve been thinking for quite some time now, how to start some articles about Microsoft VDI (Virtual Desktop Infrastructure) and RDS (Remote Desktop Services), and I’ve got it; I will just start with something simple, like the installation, then continue with services configurations. In this guide I’ll show you how to install the Microsoft RDS role services, which in previous versions of Windows it was called Terminal Services. (more…)
Removing a Domain Controller from a Domain
0There are times when you need to decommission one or more domain controllers from your domain, and don’t think you just power off that specific domain controller and put it in a closet. No…you need to issue specific commands and follow some wizard steps which safely removes the domain controller, and sets the right permissions on the server. If you don’t do this the rest of the domain controllers will try to reach the one that is disconnected, resulting in increase of traffic and error logs, as a start. (more…)
Add users in VMware vCenter
0I bet everything went great in your VMware infrastructure, until the company hired a junior admin to help you with the work. Now that’s not a bad thing, but you can’t just give him/her full permissions to your vCenter from the start, because it needs to learn the infrastructure first and get familiar with it. If adding a user to your VMware vCenter infrastructure is a challenge, no worry, I will show you how is done in just a second. (more…)
Creating virtual machines in SCVMM 2008 R2
0For those of you that are just getting started with System Center Virtual Machine Manager 2008 (SCVMM) I think this will be a useful post. After you’re done installing SCVMM is time to create some virtual machines and in this guide I’m going to show you that, so read on. (more…)
WSUS in a workgroup environment
0There are situations when client computers are not part of a Windows domain, but you still have to patch those systems using WSUS. Now I bet you ask yourself how those clients get configured if no Active Directory environment is present. I will answer your question in this guide. (more…)
Replacing VMware ESX server default (self signed) certificate
0I bet you got tired of those annoying certificate messages every time you connect to your ESX/ESXi servers. And is not just about the messages, is more about trusting the host, you or your users connect to. There are situations when you need to have a proper and a trusted certificate on you ESX/ESXi hosts, and in this guide I’m going to show you how to replace the default (self signed) certificate with a proper one. (more…)
Creating an additional domain controller in an existing domain
0Your environment is growing so you need to think about availability for your domain controller. You might think, what the heck, I’ll just restore it from backup if my domain controller fails; and you are right, but until you restore it, your users won’t be happy at all. To prevent this kind of situations additional domain controllers are needed, so if one fails others takes the charge. Another reason why you need to have multiple domain controllers is for load balancing the traffic for the domain, and improve the reliability of network services. (more…)
In-place upgrade from VMware ESX 4.1 to ESXi 5
0For those small businesses that don’t afford buying VMware vCenter and want to upgrade from ESX 4.1 to ESXi 5, an in-place upgrade is the only way to go. In this guide I’m going to show you the steps involved in the upgrade process. For this lab I have an ESX 4.1 server with some virtual machines located on the local datastore, so no iSCSI or Fiber Channel Storage is connected to the server. Even if they were connected the process will be the same. (more…)
