Since Exchange 2010, and the introduction of the document retention period it has been much easier to recover mailboxes, disconnect or connect mailboxes to users, and disable mailboxes. Exchange 2010 has introduced the personal archive, which adds a slight complication.
P2V Migration adds documentation and support of System Center Configuration Manager 2007 Zero Touch Installation!
What is better than spending a moment to kick off a completely automated process to redeliver an existing operating system as a virtual machine within a new build of Windows 7?
Hello Everyone, Just wanted to let you know about a session on Windows Server 2008 R2 Clustering and High Availability that I'm going to present today for WITPro (Winnipeg IT Pro community). Doors open at 5:30 PM, session to start at 6 PM.
Microsoft has released are some serious updates to the Exchange 2010 Mailbox Server Role Requirements Calculator, including one piece of functionality that you all have been asking for since the first version been released back in November!
Please go to Mailbox Server Role Storage Requirements Calculator updates tracking page to see what is in this new version! A blog post explaining the calculator (updated for this new version) is here and or you can download the calculator directly.
In this session introduced Group Policy Preferences and showed a number of demo's as to how it can be used in your environment to eliminate logon scripts.
Since the release of Windows 7 and Server 2008-R2 we have about 3000 Group Policy Settings available to centrally configure and manage Windows clients and servers. Though some among us might have worked with GPO settings from the early days on, knowing about the existence of each and every available setting is nearly impossible. It still happens to me that while I am configuring a specific GPO setting, I do come across other GPOs I didn't knew of yet.
Windows Firewall on Windows Server 2008 helps prevent unauthorized access to computer resources. However, if the firewall is configured incorrectly, attempts to connect to an instance of SQL Server may be blocked. To access an instance of SQL Server that is behind the firewall, you must configure the firewall on the computer that is running SQL Server.
This article helps you open the firewall ports for SQL Server on Windows Server 2008.
Don't worry, we still can Sequence Adobe Acrobat Reader 9 :). To do that we need to find MSI package of Adobe Acrobat Reader 9. Wait, wait, wait, don't go to Adobe's FTP server, you will not find there MSI file for English version :).
To get it you have 2 options:
- Request this file from Adobe, by subscribe to distribution program
- Extract it from AdbeRdr90_en_US.exe file :).
- Run the installer, and wait until the setup dialog appears asking you for a destination folder to install to.
- Without closing that dialog open, run Windows Explorer and navigate to C:\Documents and Settings\usernamel\Local Settings\Application Data\Adobe\Reader 9.0\Setup Files\READER9 .
The former solution for this issue usually was to stop the last virtual machine that they started, to reduce its memory, and then start it up again.
This solution has worked in the past – but is no longer an option with dynamic memory. The reason why this will not work is because if you stop the last virtual machine – you just leave the memory available for your other virtual machines to use – getting you straight back where you started.
For this reason, with dynamic memory Microsoft has implemented a new "Parent Memory Reserve" for Hyper-V. Here Microsoft attempt to calculate an appropriate amount memory to keep for the parent partition and ensure that virtual machines with dynamic memory enabled cannot eat into this reserved memory.
Specifically – it only accounts for the memory requirements of Hyper-V in the parent partition.
To help mitigate this issue – Microsoft is also providing a new registry entry that lets you override our parent memory reserve with your own static memory reserve. This registry entry does not exist by default – but if you go to the HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Virtualization registry key and create a new DWORD entry with a name of memoryreserve – you can then set the value to the static amount of memory that you want to reserve for the parent.
You should be warned – if you set this value too low; virtual machines will be able to use too much memory and cause performance issues for you. Equally – the higher you set this the fewer virtual machines you can run.
By setting this value to 2048 (on my laptop with 8GB of RAM) I can run multiple virtual machines and know that they will not cause Outlook / Internet Explorer in the parent partition to be affected.

But if you shut down a cluster host, say, because you're deploying a Windows Update, or a new version of a backup or monitoring client, the situation is different. Windows will use Quick Migration to move the virtual machines from one host to another - and Quick Migration is nothing like VMotion and Live Migration.
Instead of copying the VM memory and processor state across the network, the virtual machine is saved (to your SAN) on one host, then restored from that saved state on another. The difference is obvious:
