Error Crashing V4

Got a client getting crashes.
They have been having some IP conflicts and pretty sure its related.
This bit makes me think thats the case;

A transport-level error has occurred when receiving results from the server. (provider: Session Provider, error: 19 - Physical connection is not usable)

Its the big club with 1500+ capacity and they are on 192.168.1.x - 255.255.255.0 subnet.
Have advised network improvements and been asked to go down and quote.

But in the mean time, am I thinking right this will be ip conflic related.?

Sorry dont know whats up with the layout on that…

That happens when SQL Server closes an active connection. It is not clear why it happened. Any network or server issue might be considered. Also if it is SQL Server 2014 if you didn’t installed service pack 1 you can try installing it.

I don’t know if I had the same problem in V5 but Sambapos freezes almost every 5 minutes in every client, sometimes in the server too and when I was trying to do something it crashes, this problem was because I connected the clients to wifi and the computers were working in a Ethernet local area network so when I turned wifi off in clients everything worked fine.
Server has been connected to wifi since the first day so I think the problem was which network should it use.

It’s only on the one terminal and that terminal has cone up with IP conflict warning.
All others are fine.
System has been solid for well over a year.
