Can dns server assume domain name from client query with no fqdn

No, a DNS server cannot (or at least should not) assume a local  
domain. BIND 9 does not have such a feature.

Nothing says clients need to have a "domain suffix" (a local domain)  
set. And nothing says they need to be in Active Directory. DNS  
resolution should work anyway.

Is there a reason your clients can't look up the FQDN rather than a  
short hostname?
