Hi, We have just recast the IP addresses on our network, moving them from a public address range to a 192.168... range behind NAT. We use samba 3.0.10-1.4E.6 and cups 1.16 on Redhat ELS4 all running on the same machine. In changing the network addresses the internal domain names have also changed from "name.domain.org.uk" to "name.uk.domain.org". The server also runs a caching DNS for the internal network. Dig <new server name> gives the correct new address for the new server name. The problem is that when starting up samba is trying to find the cups server at the old domain name which it seems to have cached somewhere and then of course failing to enumerate the printer shares. Smbd.log shows the following ... [2006/04/24 09:00:58, 0] printing/print_cups.c:cups_printer_fn(94) Unable to connect to CUPS server auckland.mercyships.org.uk - Connection timed out ... The correct server name is now auckland.uk.mercyships.org. Cupsd.conf has the correct new domain name for the servername (trying to change this to "localhost" or an explicit IP address has no effect. Can anyone tell me where samba is finding the old domain name for the cups server?? Ashley Strickland IT Services, Mercy Ships UK Tel: +44 (0)1438 347496
