Looking at a wireshark trace, I see that the client is attempting to negotiate a session using smb v2.0 but the netapp is returning errors, starting with this. I am assuming this there is some setting on the netapp that is not configured correctly. I mean, it's smb version 2, which has been around for ever. the last error msg is "not supported" ???
