This will be my first post on my new blog. Hope that you will enjoy!
I had a KMS server installed on a Windows Server 2008 SP2. The KMS server was activated using a Windows Server 2008 KMS B key, and the KB968912 allowing Windows Server 2008 SP2 KMS to activate Windows 7 and Windows 2008 R2 was installed.
A statistic for the KMS server can be show with the cscript slmgr.vbs /dli command.
Normally a KMS server will start activate servers when the "Current Count" reaches 5 and clients when it reaches 25.
But this server would not increase the "Current Count" only the "Failed requests received" would increase.
When trying to activate a Windows 7 client I would get the error code "0xC004F074" with description "The Key Management Server (KMS) is unavailable".
I found a workaround to the problem here.
Basicly it says that you should do the following:
- Uninstall KMS license Key on host - slmgr.vbs /upk
- Install Windows Server 2008 R2 KMS license key - slmgr.vbs /ipk <Your Key>
- Activate KMS server online: slmgr.vbs /ato
- Restart the "Software Licensing" service.
So even thougt that it should work with the Windows Server 2008 key it did not. A Windows Server 2008 R2 KMS key solved the problem.
