I have KMS host running on Server 2008 R2. I can activate all the clients from the host. But when I try to activate one of our 2008 Server using the slmgr -ato command, it says product not found.. please advice.. Thanks JAZEEL

It was a KMS host before. Now I shifted to another running on R2. It seems it still acting as a KMS host.. PLease advice. How can i convert it to KMS client.

Solved this by installing the KMS client setup key on the old KMS host. http://technet.microsoft.com/en-us/library/ff793421.aspx
