Once a KMS host server is activated, do it need to renew is activation after a period of time or does it never have to contact Microsoft again ? In clear, is the KMS key never expire ?

Hello,the KMS server has to be activated once with Microsoft.But that it will work correct, you need at least 5 Windows server 2008 machines or 25 Windows Vista machines or higher OS.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights.

Hello,The KMS host key once activated does not need to contact Microsoft again unless there are hardware changes that exceed the tolerance. It's one time activation unless there are changesThanks, Darrell Gorter This posting is provided "AS IS" with no warranties, and confers no rights
