Can someone take a look at my wireshark capture and help make sense of why I can't connect?

I can't upload/attach due to low karma so here's a link: updated link

Thanks in advance.

I looked at a number of TCP streams in the capture and they all show the same behaviour, the client abruptly closes the connection with a RST after receiving the SMB2 session setup response.

My assumption is that the client isn't happy with something in the response, although I don't see the server indicating any issue in it's response.

so it's the client side? i was thinking that it would be on the other end... i'm having this issue when accessing workstations in another domain i don't have the issue when accessing servers in the same domain thanks for your help, btw

It's certainly possible that the server is generating something that upsets the clients. If it's a cross domain issue I would be looking at domain trusts.
