Unity VSA always generates eventid error 5827 on Windows 2016 DC´s

Question

Since we updated our AD environment to Windows Server 2016 we have some issues with our SMB shares on our Unity VSA. We always get the following error message on the DC´s: eventid 5827: The Netlogon service denied a vulnerable Netlogon secure channel connection from a machine account. Actually we have nothing willingly changed in the AD or on the Unity VSA. Does anyone have an idea what we can do to get rid of this error?

Take a look at this:

MS rolled out a security change to close a security vulnerability which gives the error you describe. You need to upgrade the VSA to 5.0.6 or later.
