Setting up KMS for office 2013


We have KMS server(Win2012) on our network, and we use office 2010 installed on Windows 7 PCs and Windows 8 Tablets. Whenever I install office 2010 on a workgroup PC and join to the domain and do a gpupdate and restart the PC and if I open word and File-Help- It says Product activated.

Now I have built a new Windows 7 image for one of the ICT suites, installed office 2013 and joined this PC to the domain and did a gpupdate and opened Word 2013-File-Account-It says Activation required.

We have Microsoft EES for our organisation when I log into the portal, I can see the KMS key for office 2013 listed.

My predecessors had set up the KMS server which is installed on our secondary DC server(Win2012).
I downloaded Microsoft Office 2013 Volume License Pack from the below link and ran on my secondary DC (Current KMS server) 

When I install I get the select volume activation method window, in there

I am not sure which option to choose Active Directory-Based Activation\KMS and proceed
This is the first time I am setting up the KMS, Any help to setup this much appreciated.

I also came across another member server in our network and I can see Volume activation Management tool is installed on this server and not sure why Volume activation Management tool was installed on this server and not sure if this server activates the office clients or my secondary DC is activating the office clients. see the snapshot for product keys.
(not sure if my predecessor tried to install this left half way through)

So not sure as how to troubleshoot and proceed  with KMS setup for office 2013 bit confusing. Any help to setup this will be much appreciated. Please let me know if you need any further information.

OK, first, you have to add the key for office 2013 to your KMS server.
slmgr.vbs -ipk <your kms key for office 2013>
Then activate it
slmgr.vbx -ato

This should add the key to the existing server. If you think you have multiple servers running the service and want to know which one is really being used, check DNS. In the SRV records, in the _tcp  folder, you should see a SRV record for VLMCS. this should tell you the FQDN of the current KMS server.
