The Windows Enterprise machine was activated using KMS and it has not been able to reach a your corporate KMS host or was AD activated on a domain that is not reachable currently. The activation was good for 180 days an dis now down to the remaining 17 days to reach your KMS host or your AD activated domain.
Do you have a KMS host?
Open an elevated CMD prompt.
Run slmgr /DLV.
This will tell you the KMS host that previously activated this machine and you can check if that machine is still accessible from this client machine.
See this link to trouble-shooting KMS, which includes the Event log entries and what they mean.
