Перенос Active Directory с Windows Server 2003 на Windows Server 2012 R2 является одной из первоочередных задач, которые необходимо решить в процессе миграции.

На самом деле, перенос Active Directory не несет в себе каких-либо сложностей. Нужно выполнить лишь несколько шагов, о которых будет подробно рассказано далее.

The error seem to stem from the operations master the Win 2003 server R3 it was showed the infamous JRNL_WRAP_ERROR.

To fix:

1. Stop File Replication Service on all machines

2. On the Operations Master I set the BurFlag to 0xD4.

3. Started File Replication Service on the Operations Master.

4. On the Windows 2012 Server set the BruFlag to 0xD2.

5. Started File Replication Service Windows 2012 Server.

SYSVOL and NETLOGON are now present on the Service Windows 2012 Server and the NTFrs errors/warning have stopped - Yay!.

Backing up Active Directory in Windows Server 2012 R2 with Powershell is now really easy thanks to the Windows Server Backup cmdlets provided in Powershell. Windows Server Backup allows you to create a Scheduled backup or a one time backup. In this example, I’ll be doing a one time backup but scheduling via a scheduled task to allow for more flexibility and I’ll be backing up the system state of the server.

Как я перестал беспокоиться и полюбил репликацию Hyper-V

16:43

Итак, на что я хочу потратить примерно час вашего времени:

  • Надо понять, зачем вообще нужна репликация в условиях современного мира
  • Составить чек лист из очевидных и не очень пунктов, предшествующих настройке серверов
  • Как правильно и быстро настроить репликацию встроенными средствами. Достаточно подробно, но без воды
  • Несколько советов по оптимизации процесса репликации.
  • Ни слова про продукты Veeam или других вендоров.

Export multiple Windows Server 2012 R2 Hyper-V Guests with PowerShell Part II

11:35

Expanding upon the basics demonstrated in Part I of this series, let’s now look at exporting multiple machines using a single PowerShell script. We’ll use the same director structure as outlined in Part I, but here we have a few additional challenges to overcome.

  • Selecting the Virtual Machines to export.
  • Ensuring that we only export one at a time to reduce the disk I/O and resulting disk fragmentation that will occur if simply try to export all of the machines at one time.
  • You want to export the machines while they’re in a running state.

The following PowerShell script will do the job admirably, but let’s take a look at a few key sections that make this possible.

First the assumptions:

  • HyperV Host is running Windows Server 2012 R2 as this will not work on Windows Server 2012.

Then the script:

 

Time Synchronization in Hyper-V

09:25

There is a lot of confusion about how time synchronization works in Hyper-V – so I wanted to take the time to sit down and write up all the details.

There are actually multiple problems that exist around keeping time inside of virtual machines – and Hyper-V tackles these problems in different ways.

RegDllView

regdllview

RegDllView is a small utility that displays the list of all registered dll/ocx/exe files (COM registration). For each registered file, you can view the last date/time that it was registered, and the list of all registration entries (CLSID/ProgID).

RegDllView also allows you to unregister dll/ocx files that you don't need on your system anymore. If you have dll/ocx files that don't exist on your system anymore, but their registration entries are still exist in your Registry, you can manually remove these entries by using 'Delete All Entries For Selected Files' option.

Starting from version 1.35, RegDllView also allows you to register dll/ocx files (like regsvr32), simply by dragging one or more files from Explorer folder into the window of RegDllView.

Migrating to Hyper-V from Virtual Server or Virtual PC

09:21

These instructions seem to work well for migrating guest machines from Virtual PC or Virtual Server 2005 to Hyper-V. As noted some steps may not be necessary, but this is comprehensive should you run into issues – e.g. migrating from Virtual PC to Hyper-V is not supported and machines that originated from Windows XP or Virtual PC might not work without the undocumented/unsupported steps to replace the HAL with an ACPI HAL.

Browsing Mailbox Databases in Exchange 2007 and 2010

A reader asks whether it is possible to browse through mailbox databases to view the details and statistics of the mailboxes they host on Exchange Server 2007 and 2010. You might recall this was simple to achieve using the Exchange Server 2003 System Manager tools.

The nearest equivalent feature in the Exchange Management Console is using filters in the Recipient Configuration/Mailboxes section of the console.
