Install KMS and Office KMS servers

How to configure a KMS server in Windows Server 2008 R2

Well I have had the pleasure of setting up a KMS server in our environment, and found that the documentation from Microsoft is somewhat confusing. In light of this I will write the steps I used to configure the first KMS server in our organisation for use with Windows Server, Windows client and Microsoft Office activation. These steps will only include the installation of 1 KMS server. I will add a second server in a couple of months when I have my seconds Windows 2008 R2 Domain Controller in our head office.

Installing first KMS Server

These are the steps I followed to install the KMS server. We determined that due to the number of client activations, and the capacity of our infrastructure we had no problems installing this server on our secondary domain controller. From here on we will call it DC2.

Log onto and fetch your key: “Win Srv 2008 R2 Data Ctr/Itan KMS C” – Note your key may be similar, but either way it must end in either KMS B, or KMS C.
On DC2 we run CMD with elevation
Type slmgr /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx where the last section is the Key from your volume licensing website.
Open “Windows Firewall with Advanced Security” via Start menu -> Administrative Tools.
Under Inbound Rules scroll down to “Key Management Service (TCP-In)”, right click and select enable.
Reboot the machine – note you can restart the Software Licensing service but I preferred to reboot it (seeing as the server was not in use for anything else)
net stop sppsvc && net start sppsvc
Active server after reboot. This can be done via the GUI or by executing the following command from an elevated command prompt:
slmgr.vbs /ato
Enables automatic DNS publishing by the KMS host by entering the below command in an elevated command promt. Note this should already be enabled, but just in case, we execute the command.
slmgr /sdns
Now you are done installing your KMS server.Note this will provide activation for clients and/or servers depending on the KMS key you used to activate DC2. Office KMS activation will be covered in a later section.

I do recommend verifying that the SRV record in DNS is created. Note that you should have no problems with the automatic creation if you are using the vanilla install of AD and have no specific security restrictions in DNS. To verify that the DNS record has been created open up DNS and check. Refer to the screenshot below to see where it lives:

Installing Office KMS Host

As mentioned above we have determined that the one KMS box (DC2) is suitable to do all of our activations for Microsoft products, so now we have to configure the Office KMS host on DC2. To do this we do the following:

Log onto and fetch your key: “Office 2010 Suites and Apps KMS” – Note your key may be similar. If unsure speak to your Microsoft Account Manager.
Download the Office 2010 KMS Host License Pack from the Microsoft website: Its only 903kb so wont take too long.
Execute KeyManagementServiceHost.exe from your existing KMS server> In our case its DC2. Follow the prompt to finish the setup process.
When prompted enter the KMS key for Office 2010.
Thats it. Just as easy to setup. Now you are ready to activeate Office 2010 with KMS. to help monitor this, please refer the the section below.

Administering the KMS server

I take it now you want to see whether it works and if clients can be activated. Now i will go into administering the KMS server, which will be quite brief as there is not much to it, and is really only there to aid in troubleshooting, and to have a sticky beak when implementing it. Once its running there is no real reason to keep going in and checking up on it.

All functions to view settings and make changes are done through the already used VBS script slmgr.vbs. To see all the commands simply run slmgr from the command prompt. Note to execute changes you will need elevated command prompt. You will see the following screens:

So the most common command that i used was:

Displays license information (KMS Activation Count)

cscript slmgr.vbs /dli
Displays detailed license information

cscript slmgr.vbs /dlv all
For Office specific information you can run the below command to get the info wanted:

cscript slmgr.vbs /dlv bfe7a195-4f8f-4f0b-a622-cf13c7d16864
Note I add cscript to the front of the command so that the output stays within the command window, this lets me output/scroll if there is a lot of data where as the usual vbs dialog crops the output.

Configuring KMS Clients

By default, Volume Licensing edition of Windows Vista, Windows 7 , Windows Server 2008, and Windows Server 2008 R2 are KMS clients. If the computers the organisation wants to activate using KMS are using any of these operating systems and the network allows DNS auto-discovery, no further configuration is needed.

If required you can configure the KMS client to connect to a specific KMS host, use a specific port and disable KMS auto-discovery.

When deploying KMS clients using WAIK you can use 2 different methods to prepare the client:

SYSPREP – run Sysprep /generalize which will reset the activation timer along with removing SID and a few other settings. Read about this before actually using it.
Software License Manager – run slmgr.vbs /rearm in an elevated command prompt to reset the grace period back to 30 days. Note you can only perform this 3 times in total.
You can also manually force activation of the client by using the GUI from Control Panel -> System or by running slmgr /ato.

If you want to convert MAK installations of Windows or Office to KMS, you need to change their product key, and then reactivate. Use the below keys to perform this:

You can convert Windows and Office from MAC to KMS using the GUI available, or you can use the following commands:

To install a KMS key, type slmgr.vbs /ipk KmsKey at a command prompt.
To active online, type slmgr.vbs /ato at a command prompt.
To activate by using the telephone, type slui.exe 4 at a command prompt.

To install a KMS key, type ospp.vbs /inpkey:KmsKey at a command prompt.
To active online, type ospp.vbs /act at a command prompt.

Hi Pete,
I have had a quick skim of your article and looks very informative. Thank you for sharing.

You claim – How to configure a KMS server in Windows Server 2008 R2, but you fail to say where to download the KMS server installation or how to actually install it. So how about it, put a link on where to get the bloody thing.
Ivan Dretvic 20 June, 2012 at 10:03
Hi Chuck,
Sorry if the steps were not clear enough for you but I assure you that configuring KMS on a Windows 2008 R2 server is very much possible by following my article.
The steps under heading “Installing first KMS Server” provides the steps to install it. There is no download as such because KMS ships with the product.
If you type slmgr from a command prompt you will find that all the available options in configuring KMS are presented in several scripted windows.
Sorry if the document was not clear. If time allows I will update the first section to include more information so there is no confusion in the future.
NOTE: Office does have an installation, and the link and steps were provided.
Kind Regards,

chuck, in future, before you get on your “high” horse… first acquire proper product knowledge before you crit… Great work IVAN!!!!!

Hey, thanks for the great post. Helped out a lot.
In my case, I *only* wanted to do an Office 2010 KMS host. I didn’t care (at least for now) about KMS for OS or servers.
So I just downloaded and ran the Office 2010 KMS Host License Pack software from link above on a 2008R2 server, entered my Office 2010 KMS key when prompted during install, and it did everything for me except add the firewall rule.
In other words, I never had a KMS at this site before, just ran that program, and was good to go. Even the DNS was configured by it correctly.

Hi Weave,
Thanks for the comment – I’m sure it will help others with similar requirements. I may sticky it to the bottom of the article when I get some time.

This is an example how MS should post a document on KMS. Everything I have seen from MS was to long to read and keep my attention. Thank you for the step by step instructions, perfectly writen and leaves out all the guess work.
Something worth adding, if you are moving your KMS server what additional steps need to be taken to remove KMS from the old server.

How do you add KMS keys if you have more than one KMS key? At my firm, we have 6 keys for 2008R2… Do we need to setup a seperate KMS server for each key?
Ivan Dretvic 8 November, 2012 at 09:11
Hi Jim,
The KMS key is used to activate a host running KMS with Microsoft activation server. Once activated this host can then activate an unlimited number of computers within your organisation.
You can use the same KMS key to activate a total of 6 hosts running KMS, and each host can be activated a total of 10 times each.
If you have multiple KMS keys (like we do) due to Enterprise Agreement renewals or similar situations then you only need to use the most current KMS key available, although every single one of them will work.
If you have multiple KMS keys because you have multiple Enterprise Agreements and multiple enterprises that needs activating (and they are all on the same network) then im not sure how you got yourself into this scenario, and i also dont beleive its supported.
Hope this answers your questions,

I believe you have help very much. Thank you for your prompt response. The Keys are divided by MAK and KMS. I supposed as we move towards a more KMS centric process of activation, we will no longer need the MAK keys. Thanks for the info.
