I have a Windows Server that is hosting an application that the clients access via mapped drive.  The application data and executable both reside on the server.  At least once daily, the server will become unavailable.  The users can’t access the data, the app crashed and the server is not pingable.  The workstation is pingable throughout as are all other network nodes.

 

I did a packet capture on both the server and one of the workstations (they are using a non-managed switch, so I can’t set up a span session or anything).  From the server side I see the server re-sending a lot of data between itself and the client.  On the client side I see the client seeing the transmissions as

out of sequence.

 

I have replaced the server’s patch cables, the switch and the NIC.

 

Any advice?
