Replace a damaged disk in a Windows virtual Raid 2012

Posted by Xaus Xavier Nadal 22nd on July 2012

Good afternoon.

In the previous article we saw how to create a Virtual Raid on a Windows server 2012.

http://www.megacrack.es/2012/07/22/como-crear-raid-virtual-en-windows-server-2012/

For in the next article we will see how to replace a damaged with a new mirror on another disk (existing or new) mirror.

It is if we break one of the disks in the raid, as re-add the disk and re-create the mirrored disk or raid.

The procedure we have followed has been to remove the primary disk in the virtual machine after creating the raid as shown in the previous article.

What's new in Windows Server 2012.

Posted by Xaus Xavier Nadal on June 7th 2012

Good Morning.

I pass some of the innovations that I have really enjoyed a lot.

The first developments with the Kerberos authentication will favor changing passwords to remote users who do not currently asks for a password change when connected via VPN, now you can take advantage of Kerberos authentication for dealing with remote connectivity problems related to lack of connectivity to the controller domain. To do this, you can create proxy connections message authentication and Kerberos password change for users of Remote Desktop DirectAccess or requesting access to the domain.

Compression KDC resource group. With this change, users located in large organizations where the user is a member of many groups, both local, global or universal no longer have problems of slowness or failures in authentication and data will tablets and size of the service ticket it will be much lower with subsequent improvement.

Windows Server 8 news

Posted by Xaus Xavier Nadal 13th on March 2012

As many of [Email protected] will know we have the beta of Windows Server 8 so of course, we are going to point out some features of this new operating system.

The highly anticipated first guess for most system administrators and above all is the DHCP Administrators high availability in a DHCP environment.

Yes, finally, there HAS to see everything, but and because for DHCP, it is that I have never been without DHCP, but I have not ever been free DNS and I have five copies, which is also true for performance , peroooo, because we did not have DHCP with HA?, well, I finally have Windows Server 8.

Also finally a certification authority directly as role, we need not have an IIS, we will have a role called AD Certificate Services (AD CS) to offer personalized services for issuing and managing public key infrastructure (PKI). This role will include the following functions (You can see more at: http://technet.microsoft.com/es-es/library/hh831373.aspx)

  • Certification Authority (CA)
  • Web Enrollment
  • Online Response
  • Device Enrollment Service Network
  • Certificate Enrollment Policy Web Service
  • Certificate Enrollment Web Services

Has modified the DCPROMO to make it easier to use (although not complicated, but good) with a new efficient promotion assistant that integrates with Server Manager and integrates with PowerShell of course.

This wizard will help for example by integrating adprep in the process of installing AD DS thus reducing the chances of error. Can even be run remotely via powershell, the wizard will perform a test of our infrastructure for errors so that they can afford before the promotion.

It can deploy domain controllers in the cloud (private or public) (Bufff, we are with the cloud, but that mania called a private cloud CPD), Domain Controller can be deployed through cloning.

We will have assistants to help us create a powershell scripts very easily.

The cloning method is perfect if you want to implement AD DS in several delegations at the same time (It's time that we have a domain controller by delegation, however small it may be).

The cloning process is to create a copy of an existing virtual domain controller, authorizing the source domain controller to be cloned in AD DS, and thereby prepare a configuration file that will contain detailed instructions (name, IP address, DNS, ...) With all this will reduce the number of steps to perform a dcpromo on a remote delegation.

The system is very focused on hybrid cloud environments, although suspuesto you do not need to have a CPD in the cloud to enjoy the features of this product (just missing).

AD DS Windows Server 8 be safer to virtualize (Everyone knows that to virtualize a domain controller can have problems in managing the time server and a virtual system to query your NTP on another domain controller and can have synchronization problems and provide a wrong time causing authentication errors our users) But in this case Microsoft is stepping up on the subject and created a system that is able to integrate with the BIOS of the physical machine from the virtual environment through a specific driver for it. In short, the system generates a unique identifier that is exposed by the hypervisor. This is called GenerationID (perhaps talk about it in the future) ..

Integration with Powershell is spectacular and can even display the script that is running when we make such a new GPO in the domain. This script You can use it to automate the tasks you want a simple way.

DEDUPLICATION. Back in Windows Server 2003 R2 had new deduplication capabilities although I never saw the light in companies (do not know why), even from before 2008 have tools like fdupes for linux with the-d asked you to store and wanted to file copying, but this was a good enough job manually and now it's time to leave behind those heavy backups, those increases in the capacity of our virtual machines each 2 months and enjoy a shared space between the duplicate files. (For those who do not know what you deduplication is explained in broad terms: deduplication is a system that creates pointers to the duplicate files and delete these leaving a single copy of duplicate file) this is the high level explanation, but you can find lots of information online, well at least I hope ...)

Well going to the Windows server deduplication 8 say they've gotten from deduplicate compress files and get results from 2: 1 on file servers and up 20: 1 on virtualized servers.

The system does not consume large CPU resources and is also optimized for it. Even deduplication can be scheduled for the files or even select what type of file we want to dedupe and which not.

I think I understand (And if not, I think it would be a good idea) you can dedupe data on remote servers, meaning that you can make a GEODeduplicación? ie if we have the same files on different servers even in different branches, the system will be smart enough to make a single copy of the file and pointers to other files. With the help of BranchCache could have a considerable speed in the opening of remote files, to see how the story ends, it looks great.

Well, I do not extend more than sure that you are tired of so much text.

For those who still want more I leave the link to more information:

http://technet.microsoft.com/library/hh831802.aspx

I leave also laboratory Guides Beta testing Windows Server "8" so that you can see in a practical way

Greetings and see you soon.

As solve problem with Server Manager 0x800706BE

Posted by Xaus Xavier Nadal 28th on March 2011

This article shows the step by step solution to the error Error HRESULT 0x800706BE which causes can not be opened roles inside of the Server Manager.

The steps are as follows:

Close all instances of Server Manager.

download tool System Update Readiness for Windows-based Vista, Windows Server 2008, 2008 R2 Windows Server and Windows computers 7 from the link: http://support.microsoft.com/kb/947821. (Download the Windows Server 2008 R2 x64)

When installed 15 wait minutes or so to perform patch scan of the file system and Windows registry for inconsistencies.

Check the file C: \ Windows \ Logs \ CBS \ Checksur.log y CbsUpdateState.bin for errors (Check that there are corrupt files).

0x08xxx

Verify that the following folder C: \ Windows \ system32 \ ServerManager \ Cacheno files CbsUpdateInfo.bin y CbsUpdateState.bin and if we copy from another server with the same characteristics, patch level and installed roles and start the Server Manager to remove these become.

Take ownership and give the user permissions will copy the necessary files (Corrupt) in this case megacrack.es \ xavixaus.

takeown / F c: \ Windows \ Servicing \ Packages / D and / R

cacls c: \ Windows \ Servicing \ Packages / E / T / C / G "megacrack.es \ xavixaus": F

Copy all files from a server expediently with the same roles, patch level and installed and from the following folders programs.

C: \ Windows \ system32 \ ServerManager \ Cache

C: \ windows \ servicing \ packages

Tear Server Manager and check that the problem has been solved ...

Greetings and see you soon MegaCracks.

Part 1.- How to assign GPO only to objects in AD Workstation.

Posted by Xaus Xavier Nadal 20th on March 2008

I woke up this morning with a solution to a problem that had long sought.

The problem is as follows:

I want to include a group of Active Directory as the local administrator of all computers workstations in a domain, for a team of people to manage the PC's of customers in a domain remotely, without having to know the passwords of users "administrator local "for all machines.

This can be done manually pc to pc if your company is not very big but when we speak of thousands of pc's as I was required to do so in a transparent way, I was sure it worked and it did not affect the safety of the system, ie : Could not create a GPO and apply to all objects of the domain computer and I also apply to servers.
