Hyper-V virtual machine backup script…

manojlovicl — Thu, 29 Sep 2011 10:59:27 +0000

Today my friend Marko Cepe sent me his VBS script that does great job to backup virtual machines that are running on Hyper-V.
This script does shut down virtual machine by sending shut down command to machine using integration services, then it waits virtual machine to enter stopped state, after that it does export of the machine and turns the machine back on.

Usage:

C:\SKRIPTE\> ExportVM.vbs VMName ExportDirectory

Example:

C:\SKRIPTE\> ExportVM.vbs TestVM X:\Backup\TestVM

Click, download and enjoy the script.

Comments appreciated…

My contribution to IPv6 day – Configuring IPv6 in Windows server 2008 R2 – video tutorial

manojlovicl — Wed, 08 Jun 2011 21:44:20 +0000

My contribution to IPv6 day will be this small “lab” test where I will show you some basic IPv6 configuration that you can do with Windows server 2008 R2.
Here are the videos:

IPv6 day – configuring IPv6 in Windows server 2008 R2 part 1 - http://www.screencast.com/t/Ifj2lx4hTG
IPv6 day – configuring IPv6 in Windows server 2008 R2 part 2 – http://www.screencast.com/t/PSf3q5yr4BF

What do we have in our LAB?

1. Windows server 2008 R2 with two network cards:
External – with IPv6, gateway and DNS configured
Internal – with IPv6 address only

External IP has internal class static routed on our Cisco router in front of Windows server external card.

2. Windows 7 machine with single network card that is connected to the same switch as servers’ internal card.

What will we do:

In the fist video:

First we will start with some basic checking of network configuration on server.
Then we will run netsh (I run a command prompt with “Run as administrator”) and go to
netsh / interface / ipv6

with command

show route we can see ipv6 routes currently configured – we would like to enable publishing of route that I have highlighted in the video.

set route PREFIX INTERFACE_NUMBER publish=yes

then we will run an command to enable advertising, to disable address management (so Windows 7 will generate IPv6 without help od DHCPv6) (M flag) and we will disable other stateful configuration (O flag).

set interface INTERFACE_NUMBER adv=enabled managed=disabled other=disabled

Meanwhile we are checking IPv6 connectivity from our Windows 7 machine… Windows 7 is still unable to ping outside the network…

well we need to configure some other stuff on server now… we will enable forwarding on our two interfaces (External and Internal)

set interface INTERFACE_NUMBER forwarding=enabled

still no connectivity from win 7?

last step that we need to do on our server is to advertise default route to our clients…

set interface INTERFACE_NUMBER advertisedefaultroute=enabled

So our Windows 7 sudenly start to recive ICMPv6 echo replyes from some IPv6 machine outside our network WUHU!

But Windows 7 machine is not able to resolve hostnames to IPV6 addresses – this is becouse we have now global IPv6 address configured and default gateway – so we have connectivity but we are not able to resolve hostnames as we do not have any DNS servers to do that.

On Windows server 2008 R2 I will start the installation of two roles – first DHCP role which I wil configure later and DNS role.

When the roles are installed I will configure so called forwarders on my DNS server so my clients will be able to use my server as a DNS server for their queries.

In the second video:

I will first flush IPv6 configuration on Windows 7 machine by using command
ipconfig /release6
ipconfig /renew6 (is the opposite command to regain IPv6 configuration)

Secondly I will configure DHCPv6 server by starting New Scope wizard under IPv6 settings…

I will configure prefix – this ipv6 prefix of Internal network card

Skip the exceptions and activate the scope…

You will see that Windows 7 still did not ask DHCPv6 servers for address this is becouse managed flag is set to disabled on server so…

in netsh / interface / ipv6 we need to activate managed flag by inserting this command:

set interface INTERFACE_NUMBER managed=enabled

Our Windows 7 machine can now be found in IPv6 leases on our DHCP server – but still it is unable to ping hostnames on the internet… This is becouse our DHCPv6 server is not giving DNS servers as scope options and Other stateful flag is disabled.

So we first need to add DNS Recursive Names Server IPv6 Address in our Scope options and then use netsh command:

set interface INTERFACE_NUMBER other=enabled

Yeeepppeee!!! Our Windows 7 is ready to ping hostnames on the internet – so it is able to surf the IPV6 internet…

When I am finishing this article is 8.6.2011 23:37 – this is my small contribution to IPv6 day so happy IPv6 day to all of you!

Get IP address of virtual machines running on Hyper-V – FIXED!

manojlovicl — Wed, 16 Mar 2011 14:10:48 +0000

Big thank you – goes to Max Trinidad my fellow MVP from Powershell group…

Here is errorless script - much better than mine!

Copa, paste and save as .ps1 - then run on your Hyper-V server and you will get IP’s of your virtual machines…

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

## – Use Line below to list all your Virtualization Class
#get-wmiobject -namespace “root/virtualization” -list

## – Load filter (or function first)
filter Import-CimXml{

    $CimXml = [Xml]$_
    $CimObj = New-Object -TypeName System.Object

    foreach ($CimProperty in $CimXml.SelectNodes(“/INSTANCE/PROPERTY”)){
        if ($CimProperty.Name -eq “Name” -or $CimProperty.Name -eq “Data”){
            $CimObj | Add-Member -MemberType NoteProperty -Name $CimProperty.NAME -Value $CimProperty.VALUE
        }
    }

    $CimObj
}

## – Collect WMI Virtual information
$getWmiVirtual = Get-WmiObject -Namespace “root\virtualization” -Query “Select * From Msvm_ComputerSystem” | sort-object elementname

## – Build your results from your collected objects
ForEach($v in $getWmiVirtual){
    $vm = $v.ElementName;
    $VmObj = Get-WmiObject -Namespace “root\virtualization” -Query “Select * From Msvm_ComputerSystem Where ElementName=’$vm’”;
    $KvpObj = Get-WmiObject -Namespace “root\virtualization” -Query “Associators of {$VmObj} Where AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent”;
    if($KvpObj.GuestIntrinsicExchangeItems -ne $null){
        write-host $vm;
        $KvpObj.GuestIntrinsicExchangeItems | Import-CimXml | where {$_.NAME -match “NetworkAddressIPv4″} | ft;
    }
}

## – End of Script

Get IP address of virtual machines running on Hyper-V

manojlovicl — Sun, 20 Feb 2011 15:33:01 +0000

I have been searching for an easy solution to somehow “scan” virtual machines and get their IP addresses becouse sometimes you need to find your virtual machines and it is more practical to somehow get a whole list of machines + IPs in stead of loging in from machne to machine and check IP… Well it can be done using Powershell… I have encountered an article but the problem is that here you need to put machine name on which you want to get data… I modified this script a bit so it looks like:

Get-WmiObject -Namespace root\virtualization -Query “Select * From Msvm_ComputerSystem”| sort-object elementname | ForEach-Object {$vm = $_.Elementname
write-host $vm
filter Import-CimXml
{
    $CimXml = [Xml]$_
    $CimObj = New-Object -TypeName System.Object
    foreach ($CimProperty in $CimXml.SelectNodes(“/INSTANCE/PROPERTY”))
    {
if ($CimProperty.Name -eq “Name” -or $CimProperty.Name -eq “Data”)
{

$CimObj | Add-Member -MemberType NoteProperty -Name $CimProperty.NAME -Value $CimProperty.VALUE

}
}
$CimObj
}
$VmObj = Get-WmiObject -Namespace root\virtualization -Query “Select * From Msvm_ComputerSystem Where ElementName=’$vm’”
$KvpObj = Get-WmiObject -Namespace root\virtualization -Query “Associators of {$VmObj} Where AssocClass=Msvm_SystemDevice ResultClass=Msvm_KvpExchangeComponent”
$KvpObj.GuestIntrinsicExchangeItems | Import-CimXml
} | where {$_.NAME -match “NetworkAddressIPv4″} | ft
read-host

So… Copy paste this script to an text file and save it as getip.ps1 and run it using powershell – it does need any other modules you should only run it on Windows Server where you have Hyper-V role installed… (I do not remember but I think you should enable execution policy for ps1 scripts… If you have truble executing your ps1 check here…)

By the way… This script has an error first virtual machine name will not fit in table (I do not know why ) and you will get an error when this script will try to analyze your Hyper-V host machine… I do not know how to solve this two errors if someone out there solves it please provide feedback. Thank you!

Windows Server 2008 R2 Foundation on HP ML 110 G6 – SBSBIOSLock

manojlovicl — Fri, 21 May 2010 16:59:15 +0000

NT Konferenca 2010 is almost here…

While preparing my demos for my sessions I needed to install Windows server 2008 R2 Foundation on an HP ML 110 G6 which was given to me for demos…
After unpacking and starting the server I inserted DVD with installation inside… I get this nice screen telling me Validantih HP Platform Please Wait …

After a minute I got this error – a popup windows came up with folowing message:

SBSBIOSLock

could not find the media

If you want to continue your installation you need to get to HP BIOS and change the value on SATA emulation from RAID to AHCI. It worked for me… Well leave me alone I need to finish my installation.

Windows server 2008 R2 – Direct access

manojlovicl — Mon, 20 Apr 2009 21:43:12 +0000

This will give us a brand new experience of “VPN” like experience… Check this video out…

Windows server 2008 R2 – Disk management… VHD Attach

manojlovicl — Mon, 20 Apr 2009 21:29:08 +0000

It is now possible to create a new VHD or attach an existing VHD to your Windows server 2008 R2…

Check the video…

There are some other features that you can do but it was possible also in non R2 version… That is shrinking and extending partition using Disk Management

Windows server 2008 R2 Active Directory – Recycle Bin Feature

manojlovicl — Mon, 20 Apr 2009 20:52:01 +0000

Sometimes you delete user from AD and it could cause a big headache

Well… No more. Windows server 2008 R2 Beta – which is by the way already publicly available has a new functional level for AD that allows you to activate so called Recycle Bin Feature…
In this demo you will se my AD server with a domain called demoadps.local on which I will enable this feature. As I mentioned before – functional level should be Windows server 2008 R2.

Watch the video

First of all you need to enable the feature by typing a Powershell cmdlet/command:

Enable-ADOptionalFeature ‘Recycle Bin Feature’ -Scope Forest -Target ‘domain.local‘

after that you can check for deleted items by typing:

Get-ADObject -SearchBase “CN=Deleted Objects,DC=domain,DC=local” -ldapFilter “(objectClass=*)” -includeDeletedObjects | FT ObjectGUID,Name -A

This will show you the deleted objects which you can restore by entering:

Restore-ADObject -Identity 6ff46162-15c2-4d42-8e15-2fcac5c8422e

** domain.local should be changed with your domain name
6ff46162-15c2-4d42-8e15-2fcac5c8422e should be changed with a ID that matches your deleted object…

To make it simplier I have recorded a video tutorial to do that…

0X8004010F weekend – Windows server 2008, Exchange 2007 SP1

manojlovicl — Mon, 15 Dec 2008 00:10:30 +0000

This weekend I was playing crawler… I know almost all internet sites describing the problems around 0X8004010F – damn error regarding Offline address book distribution…

But nowhere I have encountered the problem describing this error code in combination with Windows Server 2008 and Exchange 2007 SP1 with rollup 5.

Well… As I figured out it apparently does not work – if you want OAB to be distributed by Web-based distribution…

You get this error in your Outlook 2007 SP1 clients (on Windows XP and on Windows Vista)

As I can see there is somekind of permission problem becoues OAB virtual directory points to:

C:\Program Files\Microsoft\Exchange Server\ClientAccess\OAB

This directory has NO NTFS permissions for Auhtenticated users… but in IIS there is on this folder a parameter: Pass-through authentication - but as I know it can not work becouse your credentials are not covered in NTFS permissions of that folder.

But it does not work even if you give NTFS permissions to authenticated users… (you are still prompted for username and password in Outlook…)

Maybe I am missing something but weekend is almost over and my users need to use Exchange and RPC over HTTP(s) feature in their Outlooks tomorow… What I did is that I disabled Web-based distribution of Offline address book and I left only Public folder distribution. It took a couple of minutes for autodiscover.xml to update and Outlooks to get new parameters about Offline address book distribution.

Everything works correctly now…

Comments / suggestions appriaciated…
