[Samba] Connection gets closed after just a few seconds "smbd/service.c:close_cnum(1150)"

[Lund, Claus]

I'm testing the AIX binaries for 3.0.24 and have run into a problem.
Depending on how I map the share (using: \\[IP, hostname or
FQDN]\[sharename]) then the connection to the server is closed after
just a few seconds of inactivity.

The server runs on AIX5.3 with the latest fixpack. The client is Win XP
SP2.
I'm currently using 3.0.22 on our production server and don't have this
problem there (it's however a compiled from source and not the "pre-made
binaries" from samba.org).

If I use the IP address to map the share then everything works just like
normal (the connection stays open for an hr). But if I use the hostname
or FQDN to map the share then the connection is closed after just a few
seconds of idle time.

So if I map the share like this:
C:\Documents and Settings\clund>net use Z: \\10.0.88.187\refprod
The command completed successfully.

Then everything works fine.


But if I map the share like this:
C:\Documents and Settings\clund>net use Z: \\tax187a\refprod
The command completed successfully.


Then the connection is closed within seconds. Here're the level 2 logs
using the hostname to map the share. The log is identical to using the
IP except for the last two entries:

I have level 10 log files available too if anybody needs to get a look
at things in that kind of detail.

Thank you in advance,
