Hello there,
If you're experiencing an issue with Office 2019 KMS (Key Management Service) server activations where the first attempt fails due to a hardware ID binding issue, but the second attempt is successful, it could be caused by several factors. Here are a few potential explanations and solutions:
Network Connectivity: Ensure that there are no network connectivity issues between the client machines and the KMS server. If the first attempt fails due to a network interruption or connectivity problem, the second attempt might succeed when the connection is stable. Check network configurations, firewalls, and any network infrastructure that could impact the communication between clients and the KMS server.
Timing and Activation Thresholds: KMS activations have specific timing and threshold requirements. Make sure that the time on the client machine and the KMS server is synchronized accurately. Additionally, note that Office 2019 requires at least 25 unique client requests before activations can occur. Ensure that the number of client machines attempting activation meets this threshold.
KMS Server Configuration: Verify the configuration of your KMS server to ensure it's set up correctly. Double-check that the server is running the appropriate version of the KMS service, is properly activated with a valid KMS host key, and has the necessary DNS records (SRV) in place. Review the server's event logs for any related errors or warnings that could indicate configuration issues.
DNS Resolution: Ensure that the client machines can resolve the KMS server's DNS records correctly. If the first activation attempt fails due to DNS resolution problems, the second attempt might succeed if the issue is resolved. Verify that the client machines can resolve the KMS server's fully qualified domain name (FQDN) correctly.
