With the engineer's guidance, John re-entered the license keys and reactivated the licenses. To his relief, the server finally recognized the licenses, and the RDS setup was up and running.
The client had purchased a set of RDS licenses, but for some reason, the server was not recognizing them. John tried to troubleshoot the issue, but no matter what he did, the server kept showing an error message indicating that the licenses were not valid.

Determined to solve the problem, John started digging deeper. He checked the license configuration, verified the license keys, and even tried to reactivate the licenses. Still, nothing seemed to work.
