Hello, how to deny access to shared folder from a specific computer?  

I made deny for a specific computer, but this computer still open shared folder, i found that computer can do it due to SYSTEM account.

I found that i can deny access with VLAN or firewall.

On firewall i can block access from IP address, but with what service or port?

Can i deny access to network share with GPO (Windows Server 2008 R2 SP1)?
