I've also tried to look at the communication over wireshark, and I do see several SMB Negotiate Protocol requests and responses, but in all of the requests there's just "Requested Dialects: Dialect: NT LM 0.12, and in all the responses same thing, Dialect Index:0 NT LM 0.12 - which, as far as I know corresponds to SMB version 1 (?), not the 2.1 version I was hoping for... I'm lost here. I thought this was all one needed to do. So, any thoughts, insights or ideas would make me very happy. Thanks you guys!
