What to do when Windows 7 comes up with a message that the Windows Activation Status is ‘not available’ (START->RUN..-> control /name Microsoft.System), not genuine (text at the right bottom corner on your desktop background) or a key icon comes up at the bottom right notification area? Maybe you say: “What? I have an KMS/Volume Activation setup! I shouldn’t care…”.
But also in a KMS/Volume Activation environment this error can occur!
So what to do now?
Firstly, check if you have a intranet connection and if you are able to reach the Volume License Server: Make a PING onto the system listed in DNS under “Forward Lookup Zones/Domain name/_tcp/_VLMCS” (see also –> http://technet.microsoft.com/en-us/library/ff793405.aspx).
If that is the case but you still have no correct Activation status, do the following:
1.) Open an Command Prompt with administrative rights
2.) Type slmgr.vbs /dli and see if you get a product ID
If you get a error that a product cannot be listed, you need to provide a KMS setup key first and activate the KMS client manually (http://technet.microsoft.com/en-us/library/ff793409.aspx):
Setup key: slmgr.vbs /ipk 33PXH-7Y6KF-2VJC9-XBBR8-HVTHH (example for Windows 7 Enterprise)
Activate manually: slmgr.vbs /ato
