Passed the Microsoft 70-403 Exam!

This morning I passed the Microsoft 70-403 System Center Virtual Machine Manager 2008, Configuring  exam! The exam wasn’t difficult at all; I was surprised by the low technical level of the questions. I got 44 questions and I’ve cleared them in a little bit more than an hour.

Restart the sshd service by typing: #service sshd restart You can now […]

Great VM network config!

A few days ago I was visiting a customer to troubleshoot some network issues on their virtual environment. I was amazed when I looked at the network configuration of their ESX servers. Look at the picture below and judge for yourself. The guy who configured it must be a real VMware guru! 😉 Cheers! – Marek.Z

Create and start a data collector from command line using LogMan.exe.

Regarding to my previous post about “List all performance counters on a Windows computer and export it to a file”, I wanted to automate the process of creating a basic system performance counter.

Manage a Windows Machine using Windows Remote Management.

With Windows Remote Management (WinRM) you can remotely (duh! 🙂 ) manage hardware and software on your Windows machines. It’s installed by default on Windows Server 2008 and Windows Vista. I mostly use it to start the command prompt on a remote system for which I use the WinRS.exe command. Before you can use WinRM, you have to configure it at the machine you want to remotely manage. Log in with an administrative account, start the […]

Create your own custom events in the event log.

Did you ever wonder how to add some custom events to your computer system or application log? I always have but never really had the time to look it up. I was browsing the Windows Server 2008 command reference guide at Microsoft TechNet Windows Server TechCenter and I found the EventCreate.exe command. So, let’s give it a try. C:>EventCreate.exe /L Application /T Success /SO Script /ID 1 /D “The script completed successfully” This command will […]
