AD Based Activation Over KMS Activation

Posted by Awinish on October 3, 2013

After quite long, I got some free time & decided to utilize to pen down an article, which talks about new feature Active Directory(AD) based activation introduced in Windows 8 & windows server 2012 & above.

To minimize the problem of piracy, Microsoft has announced starting from windows Vista & above, office products etc, you need to activate it even though you are using Volume licensing. Volume licensing keys are basically used by corporates to activate n number of system using similar keys instead of requiring multiple keys.

key management service (KMS) is the service which can be installed on the dedicated server or collocated with other server roles to allow activation of the volume license version windows (Vista, 7, 2008, R2 etc. )& office (2010, 2013 etc.)products within premise. This server will be installed in the internal environment & caters the local request for the volume activation & KMS service running on KMS host will in-turn contact Microsoft database & verify the key, instead of each system to be activated via phone or internet. KMS can also be installed on virtual machine. If dynamic DNS is enabled, KMS host can register its SRV records automatically & domain joint client can leverage this SRV records to find KMS host for activation. You can run multiple KMS host in the environment.

The Volume Activation Management Tool (VAMT) is a free tool that one can download and use to centrally modify the volume activation method and product key for clients. It can also helps you to track the licenses, their type & many more. The VAMT 3.0
can be used to keep track of MAK keys, KMS keys, Retail keys, OEM keys etc.

Key Management Services

KMS has few downside, comparing to AD based activation of volume license version of windows operating system or office products,  you need minimum count of 25 to activate clients & for server operating system it is 5. By default, the renewal of the renewal of the key on machine happens with the KMS host automatically within the duration of 7 days & maximum duration, which client can sustain without renewal is 180 days. So, after every 180 days, you need to connect your machine or server to the KMS host to renew the key, else all sort of travel will be seen on the system. To install KMS one has to use command line interface (CLI).


  • Limitation of 25 clients or 5 server count to enable activation.
  • Installation is only via CLI.
  • For high availability, more KMS hosts are required to be installed either on VM, dedicated server or collocated server.
  • Only first KMS host register its SRV records in DNS automatically, for other KMS host, requires manual creation of the records.
  • KMS uses TCP port 1688 for client-host communication.

Active Directory-Based Activation (ADBA)

Lets understand, what is Active Directory based activation (ADBA). In the simplest term, ADBA is an optional replacement to the KMS to perform activation of Volume license version of OS or office suites. There are certain prerequisite to get this feature available to your environment.

ADBA Highlights

  • It only works with Windows 2012 & 8 operating system.
  • DFL/FFL can be windows 2008 R2.
  • You need to modify AD schema to windows 2012 (Schema upgrade requires careful considerations).
  • 180 days renewal constraint is still applied.
  • Workgroup system will be activated on domain join.
  • For renewal, the domain joined system must communicate/authenticate to the DC once in a 180 days.
  • ADBA feature is not dependent on the single computer, it uses ms-SPP-Activation attribute to store the information in AD which is available on all the DC in the domain.
  • No more threshold requirement of 25 client or 5 servers.
  • ADBA & KMS can exists together to provide activation for the legacy Windows OS or office installation.
  • KMS with ADBA together provides benefits to the windows OS or office clients which doesn’t support ADBA method.

End of Microsoft’s Masters Certification & Training Program by 1st Oct 2013

Posted by Awinish on September 2, 2013

Microsoft has decided to retire Microsoft Master’s certification and training program by 1st October. For the folks, who are not aware or heard about this program, the MCM & MCA (Microsoft Certified Master & Microsoft Certified Architect) program is one of the highest certification one can achieve towards specialization in particular Microsoft technology such as Exchange, SharePoint, Lync, Active Directory etc. The reason mentioned for the retirement for MCM/MCA is technology evaluation which requires rework on the training program. For the individual, who already holds this certificates will continue to enjoy the benefits, but MS will not accept any more request for conducting new program for this certifications.

“Microsoft will no longer offer Masters and Architect level training rotations and will be retiring the Masters level certification exams as of October 1, 2013. The IT industry is changing rapidly and we will continue to evaluate the certification and training needs of the industry to determine if there’s a different certification needed for the pinnacle of our program..”

Posted by Awinish on April 9, 2013

Presuming, many of you are aware that DNS is the heart of the Active Directory(AD) & without proper DNS infrastructure it is not possible to design and setup good AD design. It is said that before mastering the AD, master DNS first because if you are able to setup DNS design perfectly, you have avoided most of the troubles for your AD.

I was searching for the some DNS information on the Technet & found a very useful link, which points considerable quality of the DNS resources.
