KMS Issue 0xC004C003

[troma76]

We have about 2500 windows 7 machines that use KMS.  A few days ago we started to see windows, not genuine pop-up. Called Microsoft they told me the key I was using is blocked. 

When I log on to the workstation I type slmgr /ato and get the error 0xC004C003

I assumed because we entered into a new year with our Volume licensing, I needed to update the 2008 r2 server with a new key. That did not fix it, so I decided it was time to upgrade the KMS server to a new server 2012r2,  that has not fixed it.  Still getting the same error.  Any ideas?

0xC004C003 = The activation server determined the specified product key is blocked

You can also try phone activation (slui 4) but will likely need a new key.

If a volume licensing issue I'd contact them here.

i found the issue it turns out that update kb971033 has something to do with this issue. here is how you fix it 

run this from an elevated command prompt:

wusa /uninstall /kb:971033
net stop sppuinotify
sc config sppuinotify start= disabled
net stop sppsvc
del %windir%\system32\7B296FB0-376B-497e-B012-9C450E1B7327-5P-0.C7483456-A289-439d-8115-601632D005A0 /ah
del %windir%\system32\7B296FB0-376B-497e-B012-9C450E1B7327-5P-1.C7483456-A289-439d-8115-601632D005A0 /ah

del %windir%\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform\cache\cache.dat
net start sppsvc
cscript c:\windows\system32\slmgr.vbs /ipk FJ82H-XT6CR-J8D7P-XQJJ2-GPDD4 <---win 7 kms key

Good news, I would not recommend posting product keys in a public forum.

this is not an actual product key its windows public published KMS host key that correlates with win 7 pro
