[Samba] Lots of failed message in smbd.log: NT_STATUS_OBJECT_NAME_NOT_FOUND

Hello,

Samba 4.8.0, configured as ADS domain member.
Clients are windows 7 and windows 10.
We get lots of failed messages in  smbd.log, but clients can access the samba shares.

What is the cause of these entries and how can I get rid of them?

Thank you und best regards
