VAMT KMS Licensing errors RRS feed

  • Question

  • we are noticing that several of our employees are receiving activation errors when logging into their computers this morning. We have verified that we have a valid KMS key, and have tried one of our previous (still valid) KMS keys. In looking at the errors when we try to push activation via VAMT from our KMS server we at first received an error about our key exceeding the unlock limit, after a reboot of the KMS server itself we are now receiving an error about not being able to find the KMS service when trying to activate individual machines via VAMT. lastly we looked through the event viewer on the KMS server itself and found several occurrences of the error below. can anyone help? any ideas?
