Hyper-V Live Migration

Having been an early adopter of Hyper-V on Windows 2008, the improvements of Hyper-V in Windows 2008 R2 were definitely welcome with the Live Migration feature being the most useful in keeping virtual machines highly available.

Assuming you already know how to cluster your servers and understand CSV’s (Cluster Shared Volumes), configuring your server to be highly available is quite simple. You should carefully consider your host specs though because Live Migration doesn’t work with different CPU architectures. For instance, you can’t Live Migrate from a host using AMD processors to a host using Intel processors. Also, Live Migration is picky about the family of processors within the given architecture chosen, so make sure your processor specs are as similar as possible .There are ‘Processor Compatibility’ settings to allow you to migrate using different processor versions but if at all possible, try to purchase your hosts with the same specs to avoid not being able to use the Live Migration feature at all.

To use the Live Migration feature, you simply need to make your virtual machine highly available by choosing the ‘Configure a service or application’ under the ‘Services and Applications’ tab under your Cluster Management. The virtual machine has to be off in order to make it highly available. Once the virtual machine is configured and started, simply right-mouse click on the virtual machine and select “Live migrate virtual machine….” and select the cluster node. The amount of memory the virtual machine is configured to use determines the amount of time it takes to migrate it because in reality, that’s all that’s really being migrated.

From the Help Desk - Keyboard Shortcuts

Modern computers really are getting faster. But it's been said that until things happen instantaneously, they’re not fast enough. Even at the Help Desk, the "clicks", the mouse drags, opening programs... They all seem to start taking longer and longer after a while. Cry

So what can be done to speed things up?

Keyboard shortcuts can be used to cut down on the number of mouse clicks and the time spent moving through options. Windows comes with several useful shortcuts.

One I use every day is a shortcut to open Windows Explorer to browse for files - hold down the Windows key and press "E" (Win+E). This is the equivalent of opening "My Computer".

Win+D minimizes all programs, so that you can see the Desktop ("D" for desktop). This is handy when you need to find a file on your desktop fast. Conversely, if you want access to a file on your desktop, and don’t want to minimize all your windows, press Win+E to open Windows Explorer and then select “Desktop”. Your desktop is just another folder in Windows and you can work on it like any other folder in Windows Explorer.

Have a bunch of Windows open and you want to switch to one that's buried? Press Alt+Tab to switch to another window. If you like, you can press and hold the Alt key and then tap the Tab key. Windows will pop up a display showing your open windows and you can select which one you like. This keyboard shortcut becomes really handy if you have two windows that you need to switch back and forth between, say if you’re copying and pasting a bunch of elements. When you press Alt+Tab, it always goes back to the last open window, so even if you have a lot of windows open, you can use Alt+Tab to just switch between your two most recent. You can also hold down the shift key to go backwards – Shift+Alt+Tab. With Vista and Windows 7 (with the Aero 3D GUI enabled), you can press Win+Tab for a neat 3D way of picking a window.

Want to close a bunch of windows? Start pressing Alt+F4 - that's the keyboard shortcut for closing a program. Every time you press Alt+F4 another program closes, so you can repeatedly tap Alt+F4 and eventually have all your programs closed.

Pressing Win+L will lock your computer so it’s protected while you’re away from it. Nobody can access your computer without putting in your password. This is handy for quick trips to the kitchen for coffee. This is a case where the keyboard shortcut is much quicker than the combination of mouse clicks and keyboard presses normally needed to lock your computer.

Win+R opens the “run” dialog box. We use this a lot at Help Desk to get to the command prompt (type cmd and press enter), or to open Windows Explorer to a known location (you can type in a path to open it, i.e. C:\Windows).

Cntl+C and cntl+V can be used to copy and paste in most programs and in Windows. Highlight or select something (you can use cntl+A to "select all") and press cntl+C to copy it. Cntl+X is the same as "cut", when you want to move something instead of copy it. Then switch to the program you want to paste into and hit cntl+V to paste what you copied or cut. This also works in Windows Explorer and is handy for copying or moving files.

Cntl+Z is handy as it invokes "un-do" in most programs. So if you're typing or pasting a bunch of text and didn't get what you expected, just tap cntl+Z to undo the mistake.

F5 is used to invoke “refresh” on many programs, including Windows Explorer and Internet Explorer. You can also use the backspace key in IE to go back to the previous page.

Finally, it’s possible to create your own keyboard shortcuts to launch files and applications. The only caveat is that the file (or a shortcut to that file) must exist on your desktop. Start by right-clicking on any icon on your desktop and selecting “properties”. About half way down the shortcut tab, you will see “Shortcut key:”. Click in that field and press the shortcut key combination that you would like to assign to that icon. It has to be ctrl+alt plus any other key. So let’s say you have an Excel spreadsheet called “my log.xls” on your desktop. You might assign ctrl+alt+L to that icon. Then when you press that combination, that file will open.

Cool

Why We Patch

Patching refers to a process in which we, IT support, install a piece of software provided by the vendor that is designed to fix a problem or flaw.  All too often I get a request to suspend patching for a particular group of computers or asked to justify the need for patching.  Patching for an IT support organization is a very labor intensive process and one that requires a significant amount of time and follow-up to ensure that the patch has been applied properly.  It is also a process that often impacts the user performances and/or stability.  That leads to the obvious question: “Why do you patch?”  

The answer is relatively simple: We patch to protect you from them.  A more detailed explanation is that we patch to protect the company that owns the computer from unnecessary costs and to protect the company’s and individual’s sensitive data.  The patches we apply are related to security flaws in a previously installed application or Operating System.

The top 10 application vulnerabilities, according to Kaspersky Labs, for 2010 are the following:
  • Microsoft Word, PowerPoint, OneNote, Excel & Outlook
  • Adobe Flash Player, Reader & Acrobat
  • Sun JAVA client
The vulnerabilities in these applications usually result in a hackers ability to download and install their own custom program which will then allow full access of your computer to the cybercriminal.  Often they are recording the key strokes when an individual logs into their bank or credit card web site to pay bills.  Or gain access to employees personal information such as home address, social security information and phone number in order to steal their identity.  If that information is not available to them, they often use the hacked computer to share illegal content, or use that computer to hack into other computers that will contain sensitive information.  Both result in performance issues related to the computer and companies internet performance.  Which affects all users. 

According to Kaspersky lab in their 2010 first quarter review, the volume of attacks are increasing:
  • A total of 327,598,028 attempts to infect users’ computers in different countries around the world were recorded, that is 26.8% more than in the previous quarter.
  • A total of 119,674,973 malicious host servers were identified. The US and Russia were both ahead of China in terms of the number of malicious hosting servers
  • Almost any device that synchronizes with a computer is used by the cybercriminals as a carrier of malware these days. The most unusual of which has so far been a USB charger for Energizer batteries.

Attacks and vulnerabilities are increasing with no real end in sight.  As there are more attacks, there will be more patches to reduce the vulnerabilities that are found.  The result is a never ending pursuit for us to protect you from them.

Windows 2008 Print Management

If you’ve been around Windows servers long enough, I’m sure you’ve seen tasks you’ve grown accustom to in one version being changed to a location with no real reason in mind and have asked yourself many times “Why did you move that Microsoft?”. Print Management in Windows Server 2008 is no exception. Every time I open the Server Management console, I feel like I’m working on a Small Business Server and I find it takes more clicks to execute on the tasks that I need to do. For instance, it takes five clicks just to get to the place to install your printer drivers. Oh yea, I almost forgot - you have to install the role first!

Aside from that fact that you can scan your network for printers and the print drivers will be installed automatically if it’s a well-known printer model (which I think is time-saving), this doesn’t help if your print server is x64 and you have x86 clients that need x86 drivers because once the x64 drivers are installed, you can’t add the x86 drivers after the fact (at least I haven’t found a way yet). This pretty much defeats the network scan feature, so I take back what I said about time-saving.

So, if you are running your print server on an x64 platform and you have x86 clients that will be using your print server, make sure you deselect the x64 checkbox and select the x86 checkbox on the first screen after the welcome screen in the “Add Printer Driver” wizard. This will save you a lot of time.

In all fairness to Microsoft though, the ability to view the print jobs and view the printer administration web page after selecting the ‘Printers’ tab in the management console is very useful.
