[Samba] Help: issues about hostname & nameserver

if you do :? 
hostname -f?? = hostname in FQDN
hostname -d = only domainname.
hostname = the hostname itselve. 
if the command hostname gives the FQDN hostname then set the hostname again with hostname -F /etc/hostname
in /etc/hostname there should be the FQDN hostname in like hostname.domain.tld it and reboot your server.
in this example: host.name.domain.tld? the hostname = host 
name.domain.tld = subdomain.domain.tld
thats why i say dot in hostname is not RFC compliant.
you could set the correct domain search first.?? ( adjust to your own domain name. ) 
domain subdomain.domain.tld
search subdomain.domain.tld? domain.tld
## if running use own?dns first
## internet DNS servers
nameserver iphere
nameserver iphere
if this file changes every reboot, or if you use dhcp client?for your server. 
look for /etc/dhcp3/dhclient.conf? ( i use debian for you info, so dhclient.conf can be in other directory ) 
change it like this.
supersede domain-name "subdomain.domain.tld";
supersede domain-search "subdomain.domain.tld? domain.tld";
prepend domain-name-servers;
request subnet-mask, broadcast-address, time-offset, routers,
??????? domain-name, domain-name-servers, domain-search, host-name,
??????? netbios-name-servers, netbios-scope, interface-mtu,
??????? rfc3442-classless-static-routes;

this correctes the search order in /etc/resolv.conf
now resolv.conf should be always correct. 
if this is checks, next part. 
in samba's smb.conf check if these line exists
name resolve order = wins host lmhosts bcast
dns proxy = yes

if you use dns, which i think you do, and also? dhcpserver on your server which i guess also.
the you should setup dynamic dns. ( its not that hard to set this up.) 
i guess you problem is the dhcpserver/dns setup. 
check all of the above and report back.

Thanks for your reply.

But both the wikipeida (http://en.wikipedia.org/wiki/Hostname) and documents provided by CentOS (http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-sysconfig-network.html) point out that they should be? Fully Qualified Domain Name (FQDN), such as hostname.expample.com.

And also, that does not make sense for the 2nd case in the previous mail.

What's more, I'm interested in how Samba treat the server's hostname. But I failed to search it through the code.

Help, please.
