CIFS Client Clock Skew

Description CIFS client clock skew.
Cause The client clock must be within 5 minutes range from the Kerberos
server (that is Active Directory) clock.
Workaround Configure the client to clock-synch with the Active Directory (as
an NTP server) to avoid clock skews errors.
• ACLS were accidently changed by a user or script.
• ACL is corrupted after an antivirus application accidently
quarantined corresponding files.
• ACL got corrupted after data recovery by backup application due
to compatibility issues.
• ACL got corrupted after migrating data from different location by
using 3rd party application, for example, RoboCopy.
Restore the files from snapshots or backup.
a
In the case you have migrated the data from different location
b
using Robocopy application, there is a good chance you can
restore ACLs by copying only ACLs metadata, instead of re-
copying the whole data.
In case all file system ACLs' are corrupted you can restore all
c
data from the NAS replication partner.
