[Samba] Intermittent failures mapping drives.. need debugging help/sugges tions

There is a problem with a user mapping a network drive.  Sometimes
he can map it, sometimes he can't.

SAMBA:  3.0-alpha18
UNIX:   HP-UX 11.0

rsc is a valid account on the machine he's trying to connect to
(entry in /etc/passwd, decent permissions on home directory and
all parent directories, etc.)

The strange thing is sometimes it works, and sometimes it 
doesn't.  If it doesn't connect, if he reboots enough times, 
eventually it will connect.

Here's some more I dug up (snippets from the logs -- I highlited
the differences with ** at the beginning of the line):

If he does connect, the log looks like this:
