Different TreeConnect responses for different malformed Tree fields

When I used TreeConnection request with different malformed Tree fields, the response is different. 
For the Tree field in the form "\\server\share", the server responds with STATUS_SUCCESS for a malformed "server" while STATUS_BAD_NETWORK_NAME for a malformed "share", as shown in the attached file. Is it normal?

Try the same request against Windows and report back on what is returned please.

I don't believe anything looks at the '\\server' field (it's really not relevant to anything in SMB3). The share of course has to match a real exported share.

My first inclination is that this is not a bug, but if you can show Windows behaving differently I'm willing to reconsider.

Could you please give me an overview of the internal workflow of parsing the Tree field? Thanks for your time!

No, sorry. That's why we give you the source code, so you can do these things yourself :-).
