Join xp client to the domain.
Login as administrator. Work normally e.g. install the microsoft remote
tools adminpack and opera browser. All fine. Use ADUC. Fine. Login as a
user created with samba-tool and access opera installed by administrator
before. Fine.
After a while (3 hours this time):
the samba -i -d3 terminal gives:
../source4/dsdb/dns/dns_update.c:294: Failed DNS update -
NT_STATUS_IO_TIMEOUT
After which there are no more verbose dns messages as is the subject of
another thread but not a problem at the moment. We rt-clik a share or
user in explorer and select the security tab. The users and groups of
the share show as sid-rid. Wait 10 minutes. The users and groups now
show as humanly readable names. Nothing can be done in the xp client
until then and a message appears 'Naming information cannot be located
because: The specified domain does not exist' OWTTE after which we must
reboot the client and restart samba4.
Under bind9 the same config (minus the internal dns specific lines in
smb.conf) work fine. Forward and reverse pings to the xp client fail.
All contact is lost t the outside world on the xp client.
at his stage, all dig commands are from the forwarder.
Any ideas?
Cheers,
Steve
