Some very basic thoughts to Windows Azure…
Windows Azure is
- SAAS – Software in cloud – i. e. Office 365
- PAAS – Platform in cloud – for developer Application
- IAAS – Infrastructure as a service – AD, DNS, IIS, …
Considerations must be made of the sync. Dirsync.exe can be used to sync the local environment with Azure and copy user, groups and passwords. But you should prefer to establish a real real DC in Azure and do regulary synchronisation. Your local environment will be connected to Azure via VPN.
- Set up Azzure Account
- Configure Network
- Add VMS
- Configure sites
- Use DHCP (Azure has very long lease-times)
- Add VMS (DC, DNS – point to corporate DNS – take care to use non cached Disk for NTDS)
- Configure Computer Name with Option 2
- Configure Network Adapter with Option 8
For NIC-Settings via CLI you could also use the command
Do not mix it up with net (i. e. connect shares) ore netdom
(Domain Join). This could be a 70-410 topic.
For joining a server into a Domain you could also use the
Do not mix it up with net (i. e. connect shares) ore netsh (nic-settings).
This could be a 70-410 topic.
What is new in Windows Server 2012 R2 concerning to Hyper-V?
- New VMs of the second generation, called Gen2 VM. Gen1 VM actually have a very old hardware.Gen2 VMs booting faster, and the operating systems can install quicker. You use UEFI boot from virtual SCSI drives or network. Posssible guest operating systems are only Windows Server 2012 and Windows 8 or higher (64 bits each). A change or a migration from Gen1 to Gen2 VM-VM is not possible. Gen1 VM are still supported in Windows Server 2012 R2.
- Access to machines is now also possible without a network connection (Enhanced VM Interaction), clipboard, file exchange
- Live migration has been significantly accelerated by different techniques (data compression, RDMA and SMB Multichannel)
- VMs in VHDX format allow you to change the size now in operation. This only works for drives that are attached to a virtual SCSI controller.
- A VM can be exported without shutdown
- Hyper-V Replica (running machine in duplicate external data center) now offers three different intervals: 30 seconds, 5 minutes or 15 minutes. In addition, several replications can be set (eg host 1 to host 2 to host 3 – so-called extended replication).
- Shared noting live migration from 2012-2012 R2 is possible (for migration scenarios)
- Linux gets dynamic memory, online memory, online VHDX resize and new graphics drivers
- Storage QOS: bandwidth for storage is more effectively distributed. VMs that require a lot of bandwidth, can not consume the whole bandwidth with Storage QOS enabled. A minimum bandwidth can be defined. Basic unit in MS is IOPS. IOPS are 8K by default.
- Guest clustering with shared virtualDisk: eg SQL hereby can get access to the same cluster VHDx. Both machines can obtain the VHDX via a virtual SAS interface connected.
- SMB direct: Machine data can be transmitted via SMB. Several NICs may be used simultaneously. SMB Direct cards are also supported . SMB over RDMA provides high performance.
- Snapshots are now called checkpoints
- Virtual machines can be migrated to Azure
- A newly installed server with normal GUI and the Hyper-V role requires approximately 12 GB of space
- Nested Virtualization – eg Hyper-V Server on Hyper-V server is still not working. I would love to have it for lab or demo. But there aren not enough requests for it that Microsoft will implement it.
- An ISO file can not still integrate over the network. Why not? Wan’t to have all my isos in one place on a server!
The VM-generation selection in Windows Server 2012 R2
Dynamic or static RAM allocation? Windows Server 2012 R2
Display the VM generation in Hyper-V Manager
A Gen1 VM in Hyper-V Manager – looks familiar
Properties of a Gen2 VM in Hyper-V Manager – not quite as before – IDE, legacy, legacy BIOS completely missing…
The days are over when a server operating system lasts four years (and more).But a new release just nine months after the old is challenging me. OK I am one of the older IT pros.
Prerelease versions can be downloaded here at Microsoft.
At the first glance not much has changed – except for the start button.As with Windows 8.1 it doesnt lead to the start menu. Sorry 😉 The only thing you get is the mordern ui.
Much new regards the cloud. Access to cloud services is easier and safer. Work Folders promise a central repository for a variety of devices to be.
What is new for the non cloud user like me?
- NIC teaming has been improved and now works at the packet level
- Message Analyzer provides a graphical interface for analysis of network traffic
- Automated tiering storage move frequently needed data independently on faster memory such as SSD
- Mobile device management with Microsoft System Center Configuration Manager 2012 R2 and Windows Intune
- Office 365 connectivity with Windows Azure Active Directory
- Automatic activation possible (interesting with the use of Datacenter Edition)
Where can I get Active Dirctory Users and Computers on a member-server?
- Remote Server Administration Tools
- Role Administration Tools
- AD DS and AD LDS Tools
Here is a video I found on Youtube which shows the Windows 2012 R2 Core Server installation.
I got this error message while trying to demote a Domain Controller.
I checked out that the listed zones where replicated on all domain controllers. The problem persists until I set the first DNS-Server in the TCP-IP settings to the one which will be left after the Demotion and it worked.
BJTechNews has provided a very entusiastic first few at the so called start menu in Windows Server 2012 R2
He seems to be a bit disapointed (just like me).
Switching from Core to GUI is quite simple in Server 2012. But not when upgrading.
- Windows 2008/2008 R2 Full Server can only be upgraded to Win 2012 Server with a GUI
- Windows 2008/2008 R2 Server Core can only be upgrade to Win 2012 Server Core
After the upgrade is finished it can easily be switched between Core to GUI.
You can use the Delegation of Control Wizard to assign special permissions.
The following permissions can be set with one click:
- Create, delete an manage user accounts
- Reset user passwords and force password change at next logon
- Read all user informaiton
- Create, delete and manage groups
- Modify the membership of a group
- Manage Group Policy links
- Generate Resultant Set of Policy (Planning and Logging)
- Create, delete and manage inetOrgPerson acocounts
- Reset inetOrgPerson password an force password change at next logon
- Read all inetOrgPerson information
Here is a example.
- In Users and Computers click on a OU or group with the right mousekey.
- Click "Delegate Control"
But where can you revoke the rights? The Delegation of Control
Wizard has no option for it.
Revoke the rights permitted with the Using the Delegation of
Goto Users and Computers
It is important to activate
Click with the right mousekey oClick n the OU
Select the "Security" TAB
Search for the correct User or Group
