Are you asking from a UI point-of-view? A TCP RST, is not the same as the UI 
being reset - your client's Windows TCP/IP stack would renegotiate a TCP 
connection with the server. From a UI PoV you probably wouldn't see anything 
out of the ordinary (except maybe some lag).

That's what I figured.  Thanks Z.

Yes,

If the stack resets (the whole stack) then your RDP connection goes bye bye. If 
another system sends a tcp-reset to a session then only that session gets 
reset. (Basically what an IPS would do in certain situations)

One follow up question...if the stack is resetting, would an RDP connection be 
dropped as well?  ie. If I'm RDP'ing into the server and the stack gets 
reset...do I lose my connection?  Because, during the whole debacle on 
Thursday, not once was I kicked off.  Just curious.

If the stack is resetting than it is dropping all current connections. This 
would be evident in the trace by workstationA sending a packet to ServerA with 
a response of RST. Following that would be the standard 3-way TCP handshake.

I question the robustness of an app that cannot gracefully handle a reset from 
another layer. I also question why the stack would be resetting frequently 
enough to be an issue. Resetting a specific connection, sure, but the whole 
stack? Dubious allegation. Check the trace.

Morning/afternoon all...
I have a particular application that is giving me headaches.  It is 
client/server based app that is constantly crashing.  The vendor is saying it 
is a network issue:  that the network stack is resetting causing one of the 
services to crash.  I've updates the NIC drivers, the HP team drivers and 
checked the switches and even changed the ports on the switch.  I've install 
wireshark, but am having some difficulty interpreting the capture logs.  Any 
ideas on what to look for would be greatly appreciated.
Thanks
