KMS server and Windows 7

I have a KMS server that has been set up and working fine for Server 2008 and
R2.

I do not want this server to active Windows 7 clients but I believe it is.
On new Windows 7 installs, if I do a 'slmgr -dli' it says it is activated and
licensed and references my KMS server. I don't remember entering a Windows 7
KMS key on the server.

So - is there a way to deny activation of Windows 7 clients and/or revoke
those that may have already registered?

Thank you.

Yeah there should be a solution but you need to configure that :-)

The KMS is is possibly now published via your DNS and the Win7 clients do
query automatically your KMS server. Check on your DNS server ->
yourdomain.com -> _tcp -> _VLMCS

If so, you can delete this entry and set manually during your setup
(unantended) the KMS server on your servers -> slmgr -skms "IP":1688 (hope
that is correct, but you should check that).

Thank you Ramazan. Yes the KMS server is published in DNS. I'd like to
leave it there for my servers but just not have to respond to Windows 7
requests. Is that possible?

Wouldn't I have had to have added a Windows 7 key into the KMS server to get
it to hand out Windows 7 activations?

I'm not an licensing expert :-) but I think this depends on the channel of
your KMS key. What KMS channel key do you have ? A,B or C ? Depending on the
KMS channel your server is able to activate the incoming requests. Possibly
there is also a key type only for server requests. also that could be
directly verified with MS as this is also a licensing topic.

I think the easiest way for now would be to manually add the KMS server
string to the servers after they're installed (unantended, GPO,
powershell...)....
