[Samba] read_data: read failure for 4 bytes..

[B. Cook]

I have people trying to join a domain and they are getting errors.  I 
have set log level = 2 and below are the logs for that IP.

it doesn't happen all the time.. but what is it? and how do I fix it?

there is a valid machine trust..

Samba version 3.0.23b

and things from smb.conf:

interfaces = 10.20.0.230/24, 127.0.0.1
socket options = TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT 
SO_KEEPALIVE SO_RCVBUF=8192 SO_SNDBUF=8192
hosts allow = localhost, 10.20.0., 10.20.1., 10.20.100.
hosts deny = ALL

Thanks in advance..
