See
http://no.longer.valid/phpwiki/index.php/Customizing for explanation.
First you should make a directory where you edit your custom templates:
mkdir -p /etc/e-smith/templates-custom/etc/smb.conf
Then you copy the 11ServerString file as it’s server string you want to change:
cp /etc/e-smith/templates/etc/smb.conf/11ServerString /etc/e-smith/templates-custom/etc/smb.conf
Edit the /etc/e-smith/templates/etc/smb.conf/11ServerString
to what you prefer, mine is called Linux-SME-Server
Then Expand the template with this command:
/sbin/e-smith/expand-template /etc/smb.conf
Restart samba with:
/etc/rc.d/init.d/smb restart
And see the change on your windows PC in “My Network Places”
