On 100Mbps ethernet, running as root:

tcpdump -i <interface> -s 1500 host <server_IP> -w case-insensitive-clobber.pcap

For Gigabit Ethernet, you would need to adjust the -s option to be
guaranteed to capture the jumbo frames.

It could still be a server bug if samba is failing to do the right thing
when case-insensitive matching is negotiated.
