NetApp has received reports of SMB service disruptions on Storage Products related to the installation of the first version of this patch on Windows Server 2003 Domain Controllers.  Systems impacted by this patch exhibit a denial of the client logon when using NTLMv2 for communication with the Domain Controllers. This behavior is applicable to SMBv1, SMBv2, and SMBv3 clients.\r\n\r\nCarefully review the known issues associated with the Microsoft security patch.  It is always recommended that the impact of any patch be determined in a test environment prior to production deployment.","kb_title":"Potential SMB services disruption after installation of Microsoft patch KB3002657-v1 on Windows 2003 Domain Controllers","kb_unaffected_list":["7-Mode Transition Tool","ATTO FibreBridge","Active IQ Unified Manager (formerly OnCommand Unified Manager) for Linux 7.3 and above","Active IQ Unified Manager (formerly OnCommand Unified Manager) for VMware vSphere 9.5 and above","Active IQ Unified Manager (formerly OnCommand Unified Manager) for Windows 7.3 and above","Brocade Fabric Operating System Firmware","Brocade Network Advisor Software","Clustered Data ONTAP","Clustered Data ONTAP Antivirus Connector","Data ONTAP operating in 7-Mode","E-Series SANtricity Management Plug-ins (VMware vCenter)","E-Series SANtricity OS Controller Software 11.x","E-Series SANtricity Storage Manager","E-Series SANtricity Web Services (REST API) for Web Services Proxy","Element Plug-in for vCenter Server","FAS/AFF BIOS","FAS/AFF Baseboard Management Controller (BMC)","Host Utilities - SAN for Linux","Host Utilities - SAN for Windows","MetroCluster Tiebreaker for clustered Data ONTAP","NetApp Cloud Backup (formerly AltaVault)","NetApp Cloud Backup OST Plug-in (formerly AltaVault OST Plug-in)","NetApp Converged Systems Advisor Agent","NetApp HCI Compute Node (Bootstrap OS)","NetApp HCI Compute Node BIOS","NetApp Manageability SDK","NetApp NFS Plug-in for VMware VAAI","NetApp Plug-in for Symantec NetBackup","NetApp SANtricity Cloud Connector","NetApp SANtricity SMI-S Provider","NetApp SMI-S Provider","NetApp Service Level Manager","NetApp SolidFire & HCI Management Node","NetApp SolidFire & HCI Storage Node (Element Software)","NetApp SteelStore Cloud Integrated Storage","NetApp Storage Encryption","NetApp VASA Provider for Clustered Data ONTAP 7.2 and above","ONTAP Select Deploy administration utility","OnCommand API Services","OnCommand Cloud Manager","OnCommand Insight","OnCommand System Manager 9.x","OnCommand Unified Manager for 7-Mode (core package) ","OnCommand Workflow Automation","Open Systems SnapVault Agent","RAID Controller CTS2600 Legacy Engenio","Service Processor","Single Mailbox Recovery","Snap Creator Framework","SnapCenter","SnapDrive for Unix","SnapDrive for Windows","SnapManager for Exchange","SnapManager for Hyper-V","SnapManager for MS SQL","SnapManager for Oracle","SnapManager for SAP","SnapManager for Sharepoint","Storage Replication Adapter for Clustered Data ONTAP for VMware vSphere 7.2 and above","Storage Replication Adapter for Clustered Data ONTAP for Windows 7.2 and above","Storage Services Connector","StorageGRID (formerly StorageGRID Webscale)","StorageGRID Baseboard Management Controller (BMC)","StorageGRID Webscale NAS Bridge","StorageGRID9 (9.x and prior)","System Setup","Virtual Storage Console for VMware vSphere 7.2 and above"],"kb_workarounds":"<p>No NetApp software fixes are expected to address this issue.
