Not being an expert in TDS packet decodes I would appreciate some help. I have captured a sql client - server conversation of TDS packets that appears to have quite a few retransmissions from the server to the client. The first odd frame is a TDS Response Packet from the server to the client that ethereal says is a Short Frame. Then the server sends the same packet again which is marked as an Unreassembled Packet.
 
The client sends a TCP ACK. Then the server sends another TDS Unreassembled Packet followed by an identical packet marked as a TDS Response Packet.
 
In reading the ethereal docs I get the sense that Unreassembled Packets may be a false positive of the decode.
 
The general issue is that this client is at the end of a 256kbps Frame Relay Link. Users on the same local network as the server don't have any Unreassembled Frames or retransmissions. The performance at the local client is a 1 -2 second response time while the remote users see upwards of 10 seconds.
 
Am I chasing ghosts or do these packets give a clue?  Thanks in advance. - tomj
