Windows, iSCSI and NAS (Network-Attached Storage) in Test Environment
Posted Wednesday, 19 December 2007 by Misha Hanin

Recently, I worked on a project to be deployed on a Windows servers cluster.
Before setting up the production environment, it was necessary to check if one of the required applications will work on a cluster.

To those of you who doesn’t know what a cluster is, just take a look at what’s written on Wikipedia: http://en.wikipedia.org/wiki/Computer_cluster

That time, I had no extra servers for testing, so I decided to setup the cluster in a virtual environment. To do this, I created 2 Windows 2003 Servers on  my VMWARE station.
However, the biggest problem was the storage space.

Anyone who worked at least once with clusters, knows that they need a shared storage, also called a NAS (Network-attached Storage).
Unfortunately, I have no NAS in my lab, so I used another technique for my test.
If you do Googling a bit, you will find a lot of Linux-based NAS software, like FreeNAS.

However, I wanted a Windows-based software and I found probably one of the best (IMHO), which is StarWind, available for FREE in a Personal edition.
Now, I’m not going to show you how to install a cluster, I just would like to show how to connect two (or more) servers to the same Network-attached Storage by using the iSCSI technology, and how to do this in a test environment.

How to choose the right VMware Infrastructure ESX Edition
Posted Sunday, 16 December 2007 by Misha Hanin

As you probably already know, VMware ESX is an enterprise grade virtualization product by VMware. Unlike VMware Server, VMware ESX does not require an underlying operating system to be loaded first. What this means is that you get the highest virtualization performance that is possible when using VMware ESX Server.

So what is VMware Infrastructure (VI)? VI, is really just a product suite. Keep that in mind. There is really no application called "VMware Infrastructure". VI is a bundle of VMware products...

 
PXE, aka Pre-Execution Environment and Acronis - Part 2
Posted Saturday, 15 December 2007 by Misha Hanin

Since I've published article "PXE, aka Pre-Execution Environment - Part 1" I've got a lot of emails with the same question - 'Where is a Part 2?". So, here it is.

I know many Network Administrators who work with Acronis products and i also sometime work with those good products. This week i did a project for one of my clients in Seattle, WA. The main idea was to deploy an Acronis image on new servers and configure those servers according to system requirements. So, again, those servers came without floppy drive and CD/DVD :) and as all of you know, to restore Acronis image on a new machine we have to use Bootable Rescue Media, aka Bootable CD with Acronis on it. Yes, I know, that Acronis provides a products with PXE integrated, but i don't have it :) and I've used my own PXE server.

The first step I did was create Bootable Rescue Media. Then I took 2 files, kernel.dat and ramdisk.dat  from Acronis's directory and put them into C:\PXEServer\TFTPRoot\Boot directory. Well, now was the time to make a small changes to our "default" file (default file located in C:\PXEServer\TFTPRoot\Boot\pxelinux.cfg\ directory). After all those changes my "default" file now looks as follow:

DEFAULT menu.c32

TIMEOUT 300
ALLOWOPTIONS 0
PROMPT 0

MENU TITLE PXE Boot System

LABEL ACRONIS
MENU LABEL ^Acronis Bootable
kernel kernel.dat
append initrd=ramdisk.dat vga=791 ramdisk_size=32768 acpi=off quiet noapic

LABEL NetworkBoot
MENU LABEL ^Network Boot
kernel memdisk
append initrd=w98se-netboot.IMA

LABEL CleanBoot
MENU LABEL ^Clean Win 98 Boot
kernel memdisk
append initrd=W98.IMA

LABEL MemTest
MENU LABEL ^Memory Test
kernel memdisk
append initrd=W98_MemTest.IMA

The next steps were pretty simple ;), Boot, Select Acronis from the menu, Select Image for recovery and.....

Thanks to time PXE saved me I was able to spend some time in very beautiful city Seattle.

Computer Randomly Plays Classical Music :)
Posted Saturday, 08 December 2007 by Misha Hanin

During normal operation or in Safe mode, your computer may play "Fur Elise" or "It's a Small, Small World" seemingly at random. This is an indication sent to the PC speaker from the computer's BIOS that the CPU fan is failing or has failed, or that the power supply voltages have drifted out of tolerance. This is a design feature of a detection circuit and system BIOSes developed by Award/Unicore from 1997 on.

5 new technical briefs available on the Windows Home Server web site. They are:

 
Download Windows XP SP3 RC directly from Microsoft ;)
Posted Wednesday, 05 December 2007 by Misha Hanin

Today, one of my friends asked me how to get SP3 RC1 for Windows XP. Many of you know that this release available for Beta Testers, but Friend of mine is NOT beta tester. So, you can use a Hack that will allow you to download Windows XP SP3 RC1 directly from Microsoft. Windows XP SP3 will be the final service pack for really good Operating System from Microsoft. SP3 will bring a lot of bug fixes and some new features from Vista. Well, if you can't wait for official release, create a .bat file, let say xpsp3rc1.bat. Copy & Past to xpsp3rc1.bat  following commands:

@echo off
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\XPSP3 /f 2> NUL
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\XPSP3 /v RCPreview /t REG_SZ /d 1c667073-b87f-4f52-a479-98c85711d869 /f
echo XP SP3 RC1 registry key has been set.  Please check for updates in Windows Update.
pause
Once you have created the file run the file by double clicking it. Wait for the Confirmation Message on screen. The Above file adds a few entries to the Windows Registry that makes Microsoft suppose that you are a part of the Private beta program Check for new updates on Windows Update. You will see Windows XP SP3 listed in the available updates. Download and install it. Remember to Reboot :). Please note this hack is the exact way Microsoft expects its beta testers to try Windows XP SP3 out, so you don’t have to worry too much about Microsoft catching hold of you.
I tried this on Windows XP Machine and this hack worked.

PXE and Boot Disk which created at Windows XP
Posted Sunday, 02 December 2007 by Misha Hanin

Few month ago I published an article "PXE, aka Pre-Execution Environment - Part 1". In this article, I talked about a problem to use boot disk which created at Windows XP for PXE boot. I'd like to say thanks to Michael Bridge. He found a way to make the Windows XP floppy image of the netbootdisk work.

Under \\pxelinux.cfg\default
edit the default to

append initrd=.IMA raw

(add "raw" after the image name)


According to this http://syslinux.zytor.com/memdisk.php it allows access to protected mode memory. Michael Bridge, told me that he managed to get the solution on this web site:

Splitting VHDs
Posted Wednesday, 28 November 2007 by Misha Hanin

There is a great post about how to create "split VHDs" (a VHD that is broken into multiple files on the physical computer) with arbitrary sizes here:

http://www.wirwar.com/blog/2007/10/26/splitting-a-virtual-pc-vhd/

NOTE: Be warned though - only Virtual PC supports split VHDs (Virtual Server does not). 

 
Disabling Time Synchronization under Virtual PC 2007
Posted Wednesday, 28 November 2007 by Misha Hanin

When you have Virtual Machine Additions installed on Virtual PC we will automatically synchronize the virtual machines time with that of the host operating system.  For most people this is a "good thing" - but if this is something you want to disable you need to:

  1. Stop the virtual machine in question.
  2. Locate the .VMC file for the virtual machine.
  3. Open the .VMC file in notepad.

    You can use a different editor - but notepad is the safest as it is guaranteed to not change our file format to something that is incompatible with Virtual PC (which other editors have been known to do).

  4. Find the section of the .VMC file that looks like this:
    <integration>
    <microsoft>
            <mouse>
                <allow type="boolean">true</allow>
            </mouse>

    Bunch of other stuff that I am skipping over to save space...

        </microsoft>
    </integration>
  5. Change it to look like this:

    <integration>          
        <microsoft>
            <mouse>
                <allow type="boolean">true</allow>
            </mouse>
            <components>
                <host_time_sync>
                    <enabled type="boolean">false</enabled>
                </host_time_sync>
            </components>

    Bunch of other stuff that I am skipping over to save space...

        </microsoft>
    </integration>
  6. Close notepad and save the .VMC file.
  7. Start the virtual machine under Virtual PC.

Note that this will not only disable the time synchronization that happens while the virtual machine is running - it will also disable the time synchronization that occurs when you start the virtual machine.  This means that unless you are using some other method for time synchronization (network server, etc...) time inside the guest operating system will become very incorrect very quickly.

 
Release: Exchange Server 2007 Service Pack 1
Posted Thursday, 29 November 2007 by Misha Hanin

Microsoft Exchange Server 2007 Service Pack 1 (SP1) has been designed specifically to help meet the challenges of any business and the needs of all the different groups with a stake in the messaging system. Exchange Server 2007 SP1 is a mission-critical communications tool that enables employees to be more productive and access their information anywhere and anytime while providing a messaging system that enables rich, efficient access to e-mail, calendar items, voice mail, and contacts. For the administrator, Exchange Server 2007 SP1 provides advanced protection options against e-mail security threats, such as spam and viruses, as well as the tools to help manage internal compliance and high availability needs.

In Exchange Server 2007 SP1, several new features and improvements will extend the Anywhere Access capabilities of Exchange Server 2007 to help make employees more productive on whatever device they’re using, provide additional Operational Efficiency tools for administrators seeking a streamlined management and deployment experience, and enable advanced Built-in Protection for more robust high availability and compliance scenarios.

Group Policy Preferences in Windows Server 2008
Posted Wednesday, 28 November 2007 by Misha Hanin

Microsoft acquired DesktopStandard and obtained GPOVault and most of the PolicyMaker family.  GPOVault has been updated and released as Advanced Group Policy Management (AGPM), part of the Microsoft Desktop Optimization Pack for Software Assurance (MDOP).  PolicyMaker Standard Edition and PolicyMaker Share Manager will be available to Microsoft customers in two ways as "Group Policy Preferences" and will be integrated into the Group Policy Management Console (GPMC) in:

  • Windows Server 2008 (starting with November CTP)
  • Remote Server Administration Tools (RSAT) for Windows Vista SP1

Windows Server 2008 includes the new Group Policy Preferences built-in to the Group Policy Management Console (GPMC). Additionally, administrators can configure preferences by installing the Remote Server Administration Tools (RSAT) on a computer running Windows Vista Service Pack 1 (SP1).

The key difference between "Group Policy Preferences" and "Group Policies (settings)" is enforcement.  "Group Policies" enforce policy settings and prevent users from changing them.  Group Policy Preferences does not (necessarily) enforce settings to machines/users, but merely applies the settings as preferences.

"Group Policy Preferences" extend more than 20 Group Policy categories within a Group Policy Object (GPO) and enable IT professionals to configure, deploy, and manage operating system and application settings including mapped drives, scheduled tasks, power options, files and/or folders, printers, folder options and Start menu settings for Windows Server 2008, Windows Vista, Windows Server 2003, and Windows XP systems.

"Group Policy Preferences" do not require you to install any services or components onto your servers.  Windows Server 2008 includes Group Policy Preferences by default as part of the Group Policy Management Console (GPMC).  Administrators will also be able to configure and deploy Group Policy preferences in a Windows Server 2003 environment by installing the Remote Server Administration Tools (RSAT) on a computer running Windows Vista with SP1.  Both RSAT and Windows Vista SP1 will be available in the first quarter of 2008.

Although you don’t have to install any services to create GPOs (Group Policy Objects) that contain Group Policy Preferences, you must deploy the Group Policy Preferences client-side extension (CSE) to any client computer to which you want to deploy these preferences.  The CSE will be available as a separate download from Microsoft and will support the following Windows versions:

  • Windows XP with SP2
  • Windows Vista
  • Windows Server 2003 with SP1
  • Windows Server 2008 already includes the CSE.
