Posted on 2014-03-07
Last Modified: 2014-04-21

I am trying to Activate Windows 2012 Standard Server via KMS by using the following commands:-

slmgr /ipk <product id>
slmgr /skms <FQDN>:1688
slmgr /ato

But it errors with the following error:

Error 0x80072F8F On a computer running Microsoft Windows non-core edition,
run 'slui.exe 0x2a 0x80072F8F' to display the error text

Or if I try to activate it by action centre it displays the following error:-

Error code:


A security error occurred

Any ideas please

1. check your time zone and date/time should be correct
2. if already correct, set the date back and try to activate the windows

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Well, your series of commands is rather odd.  You are giving the machine an activation code with /ipk which is *NOT* normal when using KMS. And then you are trying to force activation which will, of course, fail because of the install key given previously.

In *most* instances, all you need to do is set up the KMS host and the appropriate DNS records. You should not have to log into the other OSes and run any slmgr commands. In fact, doing so would defeat the purpose of KMS. So if you can explain in more detail why you are running those commands and what your topology is, I'm guessing there is a simpe misunderstanding on how KMS works.

slmgr /dli and slmgr /xpr are both handy for quick checks.

However if you are doing a new KMS deployment, I'd install the VAMT tools. You can do a network-wide audit from there and get a much better idea of your KMS status, licensing in general, and quickly get to the root of problems that are tough to do through slmgr.

We do have other servers which do activate via KMS without any problems
So not sure what is going on here
