hpasvantis Posted October 3, 2013 Report post Posted October 3, 2013 Hi all, I am trying to setup a KMS host on a Windows 2008R2 Workgroup server for my Windows 7 clients. This server has already been activated using a MAK key but I am now trying to run the slmgr /ipk xxxxxxxxxxxxxxxx on it but getting Error: 0xC004F015. Can a server already activated using a MAK key then be made a KMS host using the above command with the newly given KMS key? Thanks in advance Pas Quote Share this post Link to post Share on other sites More sharing options...
