Problem : Malformed TDS response packet on SQL Server Packets
Capturing network frames behind a SQL server 2005 NIC i get 70% of them being:
TDS Response Packet[Malformed Packet]
It seems to affect Network requesting from that SQL server.
Anyone got a clue on what’s going on ?
TCP is clear, only the TDS encapsuled in seems malformed.

For decode, start here:

Note that the Docs go only through SQLServer 2005, and may have been interpretted after the fact. The only definitive answer is the Microsoft Source code that creates the packets. Obviously, if the decoder in WireShark is wrong, you’ll need to perform a manual decode of the packet and see if it really is mangled.
I also found this in my searches:

It’s old, but might be applicable.
