[Samba] Problem with name resolution (I think)

[Joakim Lagerqvist]

Dear all,

I believe I have a problem with name resolution and I wonder if anyone
here might have a cure for it or can point me to the right direction?

It is a fairly small network (about 30 client computers) but it seems to
be only one client computer (XP service pack 2) that has the problem.
This is what happens:
The client brows the network and find the samba server and start
browsing the folders and files. However, after a while (perhaps a minut
or two) the client gets an error message that the server is not
available or he has not permission. The client has to find the server
again and login. However if he uses the IP address of the samba server
instead, this do not happen.

I strongly believe it is a problem with name resolution and that the XP
computer "forgets" the server name after a while.

The samba server has also a proxy DNS installed to handle DNS lookups
and the server has an entry there. It is also no problem to do DNS
lookups of the samba server or using other protocols (such as pinging to
the server name). Below is a dump of smb.conf:

[global]
        workgroup = VOLVO
        server string = File sharing server
        interfaces = eth1
        log file = /var/log/samba/%m.log
        max log size = 50
        smb ports = 139
        load printers = No
        os level = 255
        preferred master = Yes

[homes]
        comment = Home Directories
        read only = No
        create mask = 0770
        force create mode = 0770
        directory mask = 0770
        force directory mode = 0770
        browseable = No


Thanks in advance!

best regards,
Joakim
