Clustered Data ONTAP 8.3 to 8.3.2P3
Some client workstations might encounter intermittent CIFS share disruptions(loss of access) that can take up to two minutes. The disruptions (loss of access) will occur on a 4H time interval and might take up to two minutes until access is restored.
This issue will occur on clustered Data ONTAP systems with versions earlier than 8.3.2.P4.
Few clients might notice the following Kerberos error:
KRB5KDC_ERR_PREAUTH_FAILED ( CIFS server account password does not match password stored in Active Directory)
In the EMS messages, the following error message is reported:
