Last Updated:

Applies to

  • ONTAP 9
  • FlexGroup
  • CIFS


  •  Unable to access shares hosted on FlexGroup volume using SMB1
    • Seeing "Access Denied" when attempting to access share from SMB1 client, such as Windows XP
    • The same share is accessible from SMB2 and up clients 
    • Not seeing any permission issues in configuration or with "sectrace" command 
    • CIFS access issues from a specific client, the EMS logs show the following which matches that clients IP:

Nblade.noSmbVerNegotiated: For Vserver "vserver", Data ONTAP(R) could not negotiate with the client "" because it does not support any of the SMB protocol versions that the client sent in the list "<PC NETWORK PROGRAM 1.0;LANMAN1.0;Windows for Workgroups 3.1a;LM1.2X002;LANMAN2.1;NT LM 0.12>".
