samba - Jan 2005 - read only share access after upgrade to 3.0.10

Hello Samba gurus.

I'm in upgrade hell after upgrading my backup rh9 server and fc2 linux
box to 3.0.10 from 3.0.7. rh9 rpm package was from the samba site and
the fc2 rpms from redhat.

I now have a system where the win xp and win98se machines on the network
can read/write to the backup share but my fc2 box only has read only
access to the share - it could write before the upgrade.

I tried downgrading back to 3.0.7 but the problem is still there - maybe
the upgrade made a change that didn't get undone with a "rpm -Uvh
--oldpackage" downgrade?

I've checked dns name resolution is working OK, tried the sticky bit
suggestion in the Howto (no joy and I didn't need it before anyway) and
upped the log level to try and find what's going on but after 3 days I
have to admit defeat and get some help...

Backup server smb.conf:

If I try smbmount from the fc2 box:

(much longer delay here than there used to be...)

or smbclient:

So much for 4 public holidays to start the year off with :-(

All help welcome.

Thanks,
