You have been subscribed to a public bug:

After upgrade to Kubuntu Jaunty from Intrepid, Samba (server) stopped
working. There are multiple machines on the network, half of them Linux,
half of them Windows XP. Samba server is running Jaunty. Samba was
working correctly before the upgrade and everybody was able to connect
to the shares, now remote connections are not working.

This is the message I am getting:
Receiving SMB: Server stopped responding
protocol negotiation failed

with debug -d6 mode I am getting:
