Stop 1 : Stop windows  browser service from your all windows clients

             netstat -tvlnp | grep smbd - shows your samba service running ports in your linux system.

Stop 2 : iptables -I INPUT 1 -p tcp --dport 445 -j DROP  - Run it on linux system
Stop 3 : Check using nmap - It shows you 445 as a filtered port.


Above steps may solve your problem.
