So to reset the license key for a Vista client you would run this command;

slmgr -ipk YFKBB-PQJJV-G996G-VWGXY-2V3X8
slmgr -ato 

Set KMS

While we wait for the incorrect KMS servers to be removed from the domain, you can manually direct the Vista client you are having trouble with to a specific server running KMS by running this command;

slmgr –skms myserver.domain.com
slmgr -ato
