Samba browser fail

[Peter Smith]

Hello again,

I have Googled all day without finding anything helpful.

I am running RedHat 7.3, kernel 2.4.18-3, samba 2.2.7-security-rollup-fix,
in an NT4 domain.

This system was running well until I reinstalled the OS.  I am using a copy
of the smb.conf and so on that were working before.

Now, while samba seems to be rinning OK, and the system can mount Windows
shares without problems, Windows machines cannot see the samba machine at
all.  There is an error report on browsing problems every 15 minutes.

I append output from the log.nmbd file, starting from where the samba server
successfully joined the NT domain, followed by the [global] section of
smb.conf.

Has anyone come across this before?

Thanks for all your help in the past,
Peter Smith
