In remote site you need to configure dns-suffix, while in main site you 
don't need it. this because i believe that the server use samba to 
broadcast the name.
in remote site with dns suffix enable, it automatically add the 'domain' 
into the host, thus change the host of the into fqdn.
so if you ping abc, it will automatically try to use abc.domain.com

while in main site, it do not need the dns-suffix, because it will use 
the name that broadcast from the computer. for small lan it can works, 
but for big lan, it usually failed.

usually we add the dns suffix in dhcp server, but for small lan, we can 
add it manually.

dns suffix similar with search entry in resolve.conf.

try to add dns suffix in your remote client, and see if that works.
